How quickly does the cross section fall as neutron energy goes up? Can you relate them as an inverse proportion?

Being cold is just another way of saying that they are moving very slowly relative to the target atoms. It would seem that the motion of the target atoms themselves would tend to defeat the entire concept of ultra cold neutrons since their relative motion would be so much greater. Why would it not be necessary to keep both parts of the equation ultra cold if we are speaking of relative motion? The implication is that it would make very little difference in performance whether or not the generated neutrons were cold relative to our observation point.

It is based on the nuclear capture reactions that occur when boron-10, which has an extremely large cross-section for neutrons, is irradiated. If even tiny amounts of boron/borax was added to the periphery of the LENR experiment – the one where putative ultracold neutrons were present - there should be a bremsstrahlung or secondary radiation signature which is detectable by specialized medical equipment or even a Geiger counter. The nuclear reaction is: 10B + n → [11B] → α + 7Li + 2.31 MeV. The fast alpha and Li ion are absorbed at once – which kills the cancer, but there is tell-tale secondary radiation, which would essentially prove the ultracold neutron was present.

A charge with angular momentum is experiencing an acceleration (in the classical mechanical sense of angular menumtum) so it should also lose angular momentum through a process of radiation. In classical physics the process of radiating energy is expected to be continuous from infinite to zero, which means there is no minimum energy state. This is true, when there are no other factors involved. However in atoms, the electron is restricted to occupying resonant states. It is the resonances that are responsible for the quantization. So your proposal of a minimum energy state is different from classical physics but it is also different from quantum physics because the process of radiation is continuous, rather than discrete, above that the minimum. Not quite. Above the ground state, the electron is still restricted to resonant states, and hence photon emission is also quantized. (Only resonant states are even momentarily stable.) Not only is it quantized, but restricted to transitions in which the total angular momentum changes by h_bar, which is the angular momentum of the photon. It is this latter restriction which gives rise to the selection rules of QM. (Not all possible transitions are allowed.) Forbidden transitions have very weak spectral lines, and IMO can only occur at all when the electron can also exchange angular momentum with something else during photon emission. The exchange with something else allows the total angular momentum imparted to the new photon to be precisely h_bar. My model differs from QM in that I propose that below the ground state, the electron spin becomes less than that commonly accepted as the intrinsic spin of the electron. (take my use of the word spin with a grain of salt.) This abstract seems to support your theory as long as the electron's displacement is small relative to its size. http://link.springer.com/article/10.1007%2FBF00715060 Harry

A charge with angular momentum is experiencing an acceleration (in the classical mechanical sense of angular menumtum) so it should also lose angular momentum through a process of radiation. In classical physics the process of radiating energy is expected to be continuous from infinite to zero, which means there is no minimum energy state. This is true, when there are no other factors involved. However in atoms, the electron is restricted to occupying resonant states. It is the resonances that are responsible for the quantization. So your proposal of a minimum energy state is different from classical physics but it is also different from quantum physics because the process of radiation is continuous, rather than discrete, above that the minimum. Not quite. Above the ground state, the electron is still restricted to resonant states, and hence photon emission is also quantized. (Only resonant states are even momentarily stable.) Not only is it quantized, but restricted to transitions in which the total angular momentum changes by h_bar, which is the angular momentum of the photon. It is this latter restriction which gives rise to the selection rules of QM. (Not all possible transitions are allowed.) Forbidden transitions have very weak spectral lines, and IMO can only occur at all when the electron can also exchange angular momentum with something else during photon emission. The exchange with something else allows the total angular momentum imparted to the new photon to be precisely h_bar. My model differs from QM in that I propose that below the ground state, the electron spin becomes less than that commonly accepted as the intrinsic spin of the electron. (take my use of the word spin with a grain of salt.) This abstract seems to support your theory as long as the electron's displacement is small relative to its size. http://link.springer.com/article/10.1007%2FBF00715060 This abstract appears to assume that radiation is always possible, whereas I think that it is only possible when h_bar change in angular momentum can occur.

However, there are classical electron models with extended charge distributions which can accelerate and/or deform without radiating. Can a model be contrived that will undergo radiationless motion while accelerating (on the average) over a distance large compared to its size? The answer is no: we prove that the “center” of the electron is always closer than the electron “diameter” to a fictitious point undergoing constant-velocity motion, if the electron's motion is radiationless.

Re: [Vo]:Re: CMNS: only a perfect LENR theory should attack other theories
Dave, a continous charge distribution presents another problem. Why doesn't this _electric form_ spontaneously distintergrate from internal repulsion? I can think of two solutions: a) the electric form has a distinct hypothetical internal structure which binds it together, b) or the electric form has two fundamental characteristics. The contents of the electric form are self-attractive but those contents appear repulsive to other electric forms. My preference is for the latter because it is less complicated and more evocative.

RE: [Vo]:Re: CMNS: only a perfect LENR theory should attack other theories
Well, Robin - this appears to be neither actual neutrino pair production (as opposed to cosmological theory), nor relevant to LENR, since it is hypothetical pair production in collapsing stars... therefore, IMHO - nothing has changed and it still requires a major miracle to suggest that that virtual neutrons, derived from f/H - can happen routinely, or even at all, in LENR. Why go that far? If we are counting miracles, and trying to conserve them g then Mills' theory alone can account for the excess heat with only one miracle... redundant ground states. OK maybe two or three but anyway, there is no proof of nickel transmutation in relative proportionality. It is almost a non-issue. Then there is Piantelli, who claims to show RXF evidence of transmutation elements together with excess heat. There are low counts of these, and when extrapolated to surface area and time - could be a hundred-thousand times too low to account for the excess heat. Even if real - this is arguably a minor phenomenon which did not show up in the Thermacore nickel, which produced excess heat for a year and was tested with the same technique. In short, these trace elements can be written-off as a QM tunneling by-product of a dominant reaction, which does not leave much transmutation. 99.% of excess heat must be coming from elsewhere. -Original Message- From: mix...@bigpond.com Can you provide any citation for neutrino-antineutrino pair production in actuality?

Re: [Vo]:Re: CMNS: only a perfect LENR theory should attack other theories
Lou, I wish it was great work. Unfortunately, there was an important flaw once again. From Robin's Web site I obtained the total cross sections, and from your Web site I obtained the neutron capture cross sections. It is the total cross section, only one component of which is the neutron capture cross section, that should be used in the attenuation calculation. As a result, I was to a certain extent comparing apples to oranges. The primary outcome is that the data that were presented are harder to interpret than they should have been, but I think they still give a useful order-of-magnitude estimate. This same error also appears to have been behind my conclusion, below, that your and Robin's Web sites give different maximum values for the cross sections. What seems to be going on is that there are resonances that cause the total cross section to go way up in the KeV range, but the absorption cross section, from both your site and Robin's, remains smaller in that energy region than in the low energy region of around 1E-3 to 1E-5 eV. So once one avoids confusing a graph of the total cross section with that of the absorption cross section, the two sites appear to agree fairly closely.

In reply to Eric Walker's message of Sun, 24 Mar 2013 12:39:44 -0700: Hi, [snip] Lou, I wish it was great work. Unfortunately, there was an important flaw once again. From Robin's Web site I obtained the total cross sections, and from your Web site I obtained the neutron capture cross sections. It is the total cross section, only one component of which is the neutron capture cross section, that should be used in the attenuation calculation. ...maybe, however neutrons that bounce around without being absorbed, still contribute to the total. IOW if you are trying to calculate how many escape from the material, then only the neutrons that are actually absorbed/captured won't make it. The rest are free to continue trying to get out. ...however, that having been said, the path that the bouncing neutrons follow would be longer because of a random-walk. Since the path is longer, their chances of being captured increases...but maybe this is already included in the concept of cross-section? BTW I also think you should be using the thermal cross-section, i.e. the cross-section at the temperature of the experiment. That should be at an energy of roughly 0.025 eV, which is a commonly used value, for just that reason. Regards, Robin van Spaandonk http://rvanspaa.freehostia.com/project.html

In reply to Harry Veeder's message of Sun, 24 Mar 2013 13:13:10 -0400: Hi, [snip] Classical EM theory says a charge undergoing acceleration should radiate energy. A charge with angular momentum is experiencing an acceleration (in the classical mechanical sense of angular menumtum) so it should also lose angular momentum through a process of radiation. In classical physics the process of radiating energy is expected to be continuous from infinite to zero, which means there is no minimum energy state. This is true, when there are no other factors involved. However in atoms, the electron is restricted to occupying resonant states. It is the resonances that are responsible for the quantization. So your proposal of a minimum energy state is different from classical physics but it is also different from quantum physics because the process of radiation is continuous, rather than discrete, above that the minimum. Not quite. Above the ground state, the electron is still restricted to resonant states, and hence photon emission is also quantized. (Only resonant states are even momentarily stable.) Not only is it quantized, but restricted to transitions in which the total angular momentum changes by h_bar, which is the angular momentum of the photon. It is this latter restriction which gives rise to the selection rules of QM. (Not all possible transitions are allowed.) Forbidden transitions have very weak spectral lines, and IMO can only occur at all when the electron can also exchange angular momentum with something else during photon emission. The exchange with something else allows the total angular momentum imparted to the new photon to be precisely h_bar. My model differs from QM in that I propose that below the ground state, the electron spin becomes less than that commonly accepted as the intrinsic spin of the electron. (take my use of the word spin with a grain of salt.) Regards, Robin van Spaandonk http://rvanspaa.freehostia.com/project.html
Re: [Vo]:Re: CMNS: only a perfect LENR theory should attack other theories
This is provides a summary of eight distinct failed models of the hydrogen atom which the preceded the Bohr model. http://skullsinthestars.com/2008/05/27/the-gallery-of-failed-atomic-models-1903-1913/ As I have argued recently, I think the key to explaining cold fusion phenomena depends on a flawed model of the atom. The advantage of a failed model is that it describes atomic arrangements which are _not stable_. Only unstable arrangements can produce the observed anomalies. The atomic model provided Quantum mechancis and the standard model is meant to be _stable_. It will never yield the observed anomalies, because it was only intended to produce and reproduce stable matter over time. However, there is more to life and to matter than the reproduction of an existing order. Here is a link by the same blogger on acceleration without radiation: http://skullsinthestars.com/2008/04/19/invisibility-physics-acceleration-without-radiation-part-i/ He concludes by saying: Ehrenfest’s prescription made plausible the possibility of a stable atom consisting of orbiting or accelerating electrons. Alas for his paper, by 1913 Bohr had proposed his model of the hydrogen atom which could explain the atom’s unusual emission properties. As time progressed, scientists came to realize that ‘loopholes’ in classical physics were inadequate to explain the observed behaviors on the atomic level, and that a new theory was needed to account for all the new and strange observations: quantum mechanics. Ehrenfest’s prescription seems to have been mostly forgotten in the quantum hubbub which ensued. While Ehrenfest's approach can explain a stable hydrogen atom, it is not clear from this if it can explain the spectrum of the hydrogen atom. Anyway, to reiterate we do not need atomic models which are consistently stable. harry On Mon, Mar 25, 2013 at 12:22 AM, Harry Veeder hveeder...@gmail.com wrote: The planet Saturn comes to mind!

The important issue is that each tiny portion of the loop radiates a signal as it accelerates, but that the integration of all of the individual signals balance out and results in no net radiation. A circular loop of current will thus demonstrate a near field which is the magnetic moment of the loop, but does not generate a far field of radiation. The near field component of the signal does not result in energy loss with time. The motion of a single point charge does result in a far field radiation pattern since it accelerates along the circular path and does not have a balancing mechanism. The trick is in the balance. For the above reasons there would be no energy loss as a result of the current flow if it consisted of a continuous charge distribution orbiting a nucleus. That is not true for a point charge following the same path.

Miracle 1 - SPPs couple with photons of light to become activated. There is little or no light in electrolysis LENR experiments - but some light exists in plasma glow or Mills reactions. If W-L want to cover electrolysis, then they should demonstrate the reality of light photons, which are absent. Blackbody radiation is not sufficient. Such coupling between collective oscillations creates local nuclear-strength electric fields in the vicinity of the patches. Miracle 2 - Nuclear strength is MeV. There is no evidence of MeV fields or even keV fields. These would be easy to document if they were present. Nuclear-strength electric fields produce x-ray radiation which is largely absent. SPP electrons bathed in such high fields increase their effective mass, thus becoming heavy electrons. Miracle 3 -Heavy electrons can apparently form near absolute zero, and then rarely - but there is no evidence of them forming at all at elevated temperature. Widom and Larsen propose that heavy SPP electrons can react directly with protons, deuterons, or tritons located in surface patches through an inverse beta decay process that results in simultaneous collective production of neutrons Miracle 4 - There is no known EC reaction with hydrogen - that is an absurd invention which is completely without precedent. Widom and Larsen propose two, or three neutrons, respectively, and a neutrino... Collectively produced neutrons are created ultra-cold; Miracle 5 - neutrinos are rarely captured in matter. This is even more outrageous than miracle 4. Widom and Larsen propose that such neutrons they have ultra-low momentum and extremely large quantum mechanical wavelengths and absorption cross-sections compared to typical neutrons at thermal energies. Miracle 6 - There is no evidence of this kind of neutron in all of physics - and ultracold neutrons, which are well-known, are not similar to the W-L concoction; but they should be if this proposal were to be taken seriously. Finally, Widom and Larsen propose that heavy SPP patch electrons are uniquely able to immediately convert almost any locally produced or incident gamma radiation directly into infrared heat energy, thus providing a form of built-in gamma shielding for LENR nuclear reactions. Miracle 7 - This is completely beyond belief. There is no evidence of gammas being converted to infrared in all of physics. Many observers who have followed LENR from the beginning are rightfully left in a state of what can only be called disgust at the shameless hucksterism (and attempted alteration) of established physics on display here. Heck ... one or two miracles should be enough for any theory, no?

In reply to Eric Walker's message of Fri, 22 Mar 2013 01:34:47 -0700: Hi, [snip] Lou, If LENR neutrons are indeed generated as proposed by W-L, almost all will be in the thermal range - quite a low momentum by fusion standards. They speak about ultra low momentum neutrons, which I think is significantly lower than thermal energies. These would then collide with nickel substrate atoms in inelastic and elastic collisions as well as be absorbed. The highest absorption cross sections in the graphs you point to for nickel are ~1000 for 63Ni and ~1 for 59Ni. 63Ni is only synthetic, and 59Ni exists only in trace quantities, so in general the absorption cross section for unenriched nickel will be lower than these. According to the charts, the cross section for 58Ni, the most common isotope (68 percent), is ~100 barns, and that for 60Ni (26 percent) is ~50 barns. So I think you would take the weighted average of these to get an upper bound on the absorption cross section of a block of normal nickel; e.g., 100 * .68 + 50 * .26 = 81 barns. That would be the upper bound, I think, neglecting other isotopes that exist in small amounts. I looked, and it is difficult to pin down exactly how to calculate the half value layer (the amount of material needed to decrease the intensity of an incident neutron beam by half) starting from the microscopic total cross section. Here we have the absorption cross section rather than the total cross section. The other two relevant cross sections -- elastic and inelastic -- are going to bounce our neutrons around and then out of the system, so I wonder if they can be neglected. It seems that shielding thickness is something that is experimentally determined and not calculated analytically so much, although perhaps Robin or someone else can help us out with a calculation. The mean free path (mfp) should be (roughly) the atomic volume divided by the cross section. For a cross section of 81 barns and Ni, this works out to 1.351 mm. The fraction that gets transmitted is e^(-d/mfp) where d is any given distance. In this case e^(-d/1.351mm). So for a thickness of 10 mm, you get a transmission fraction of 6.1E-4 = 0.061%. For 1 mm you get 47.7%. Note however that the absorption cross section increases as the speed of the neutrons decreases, hence WL's emphasis on ultra cold.

The only question is, would the electron be kept by the new nucleus, resulting in neutron creation, and a heavier isotope of the original nucleus, or would it be ejected resulting in a nucleus of the next element in the periodic table? (If past experience is any guide, then likely sometimes one, sometimes the other). e.g. H + 58Ni - 59Ni or H + 58Ni - 59Cu As for outright capture of an electron by any nucleus having a transmutation effect, you must realize that the proton consists of three quarks, like the neutron - but NOT the same three.

Hydrogen and deuterium are stable and cannot decay by EC. Nickel is not known to undergo EC either. The electron capture alone would be one miracle, but it would not be enough. As for outright capture of an electron by any nucleus having a transmutation effect, you must realize that the proton consists of three quarks, like the neutron - but NOT the same three. This is why EC alone is not enough to change a proton into a neutron. One of the quarks must be replaced for the change to occur. An electron anti-neutrino in combination with the electron is one way this can be done, and that is one of W-L's seven miracles. This is due to conservation of baryon number and other details, which are above my pay grade to explain. Baryon number is conserved in the interactions of the Standard Model, so violation of that would require another miracle, equivalent to conservation of energy. The neutron consists of two down-quarks and one up-quark with heavier charge, and the decay of one of the down quarks into a lighter up quark can be achieved by the interaction of a W boson but that does not normally happen the other way. This means the neutron decays into a proton (which contains one down and two up quarks), an electron, and an electron antineutrino. The reverse can happen, but not without the neutrino. Neutrinos are seldom absorbed by matter. In an LENR cell, a few neutrino absorptions per year could be expected. That is the third or fourth miracle. I lost count. Miracles do happen, and the Standard Model can change if and when this is proved; and maybe three interconnected miracles can happen at once to change the model, due to some factor which is yet unknown. Seven is a long way beyond the pale, all the way to Tipperary. … especially the last one - about gammas being ~100% downshifted to IR. ROTFL. The standard model, I assume, is predicated on the conviction that QM is correct and also necessary. It is felt necessary because it explains the apparent stability of matter which CM could not do. However, the belief that it necessary comes at a cost. It leads to the standard model which teaches that elemental transformations either require tremendous force to bring about, or where they do occur spontaneously in radioactive materials, those materials become prized commodities like exotic animals or slaves. From the perspective of classical physics electrons naturally spiral into the nucleus. Traditionally this is a regarded as fatal flaw, but sometimes a flaw can be desirable. The lattice lets the loaded hydrogen express some classic shortcomings. Harry

I've gone back and corrected the calculation to take into account the missing isotopes. This time I obtained upper and lower bounds for the total cross section, from both Robin's Web site [1] and Lou's site [2], and I did the calculation using Robin's method along with a modified version of that method. Here are the estimated upper and lower bounds for the total neutron cross sections for nickel as it is found in its natural isotopic abundances. The combined cross sections are the weighted values of the cross sections for individual isotopes of nickel. UB Kaeri: 206 barns LB Kaeri: 45 barns UB NDS: 94 barns LB NDS: 29 barns On the basis of these cross sections, I calculated the upper and lower bounds for the transmitted fraction of an incident beam of neutrons at 1mm and 10mm, using Robin's approach as well as a modified version of Robin's approach relying upon the mean free path described in Wikipedia's article on the neutron capture cross section [3]. The two sets of calculations agreed to within two degrees of precision, which was nice to see. Since they agreed, I'll just give the transmitted percentages using Robin's approach: UB, 1mm: 76.6 percent LB, 1mm: 15.2 percent UB, 10mm: 7 percent LB, 10mm: small For 1W of power being generated by way of neutron capture, assuming around 10 MeV per capture, there would be about 624 billion neutrons generated per second. The number of neutrons per second that would be transmitted through 1mm and 10mm of inactive nickel shielding would be: UB, 1mm: 478 billion LB, 1mm: 94 billion UB, 10mm: 43 billion LB, 10mm: 4000 This assumes that there are no neutrons being generated in the nickel shielding surrounding the active core, an assumption that runs counter to conjecture that LENR (in Pd/D) is a surface effect. An interesting thing that I discovered as I was looking into this was that Robin's Web site and Lou's Web site disagree significantly on what happens to the total cross sections when the energies are small. In general, Robin's Web site gave values that were well below the maximums, at around 10E-4 MeV, while Lou's site gave values that were highest at the very lowest energies, around 10E-10 MeV. I'm not sure what was going on there. Just to be safe, the above calculations make use of both the cross sections at the lowest energies as well as the maximum values for the cross sections. It interesting to note that the combined cross section can be expected to go way up as 58Ni transmutes to 59Ni, which normally exists in trace amounts but would build up over time, as 59Ni has an extremely large neutron capture cross section. Note that nickel would become dangerously radioactive over time as it was activated under this kind of neutron flux.

Lou, If LENR neutrons are indeed generated as proposed by W-L, almost all will be in the thermal range - quite a low momentum by fusion standards. They speak about ultra low momentum neutrons, which I think is significantly lower than thermal energies. These would then collide with nickel substrate atoms in inelastic and elastic collisions as well as be absorbed. The highest absorption cross sections in the graphs you point to for nickel are ~1000 for 63Ni and ~1 for 59Ni. 63Ni is only synthetic, and 59Ni exists only in trace quantities, so in general the absorption cross section for unenriched nickel will be lower than these. According to the charts, the cross section for 58Ni, the most common isotope (68 percent), is ~100 barns, and that for 60Ni (26 percent) is ~50 barns. So I think you would take the weighted average of these to get an upper bound on the absorption cross section of a block of normal nickel; e.g., 100 * .68 + 50 * .26 = 81 barns. That would be the upper bound, I think, neglecting other isotopes that exist in small amounts. I looked, and it is difficult to pin down exactly how to calculate the half value layer (the amount of material needed to decrease the intensity of an incident neutron beam by half) starting from the microscopic total cross section.

Eric, Says that slow neutron is produced and absorbed by atoms in a LENR device. In the order of 6.24E11 neutron captures per second for 1W, as you said, some atoms which have received an absorbed neutron will become radioactive, emitting gamma. Example: 58Ni + n - 59Ni - 59Co + e+. We should easily detect e- + e+ = 2 gammas 511KeV with a 100$ Geiger counter. Anyway, it is not good to play around such a reactor in those conditions.

Re: [Vo]:Re: CMNS: only a perfect LENR theory should attack other theories
Eric, If the W-L theory is correct, I cannot see how neutrons would form in a thermal bath and would be cooler than their environment. What would be the cooling mechanism? Moreover, given the high absorbing cross sections over a very wide range of thermal energies, I think you are misinterpreting the term ultra low momentum neutrons. There is no need to postulate the existence sub-thermal neutrons. Trying to calculate transport of thermal neutrons in such a complex environment is extremely challenging. Moreover, don't forget we may be dealing with collective/coherent phenomena - not isolated uncorrelated free space events. Many LENR researchers promoting different theories concur on this. This could change calculations dramatically, e.g., as in lasing, Mossbauer effect, superconductors, ... Neutron emissions have been reported - possibly real, possibly an artifact. I do not know whether LENR exists, or, if it does, which theories are valid. I am perplexed, though, that some, whose own beliefs are derided by main stream science, are so eager to persecute. Maybe they are smarter than the rest. Maybe not.

Re: [Vo]:Re: CMNS: only a perfect LENR theory should attack other theories
The polariton exists in a state of Quantum Mechanical superposition with the other members of its ensemble in a Nano-cavity. This is critical for the thermalization of fusion energy because the polariton will share its energy between all its entangled ensemble members when the fusion event occurs. This transfer of energy results in decoherence of the entangled states. The nano-cavity will rapidly reinitiate the BEC and the next fusion of a polariton can occur. Quantum complementarity is the essential feature distinguishing quantum from classical physics. When two physical observables are complementary, the precise knowledge of one of them makes the other unpredictable. The most known manifestation of this principle is the property of quantum-mechanical entities to behave either as particles or as waves under different experimental conditions. The link between quantum correlations, quantum nonlocality and Bohr’s complementarity principle was established in a series of “which-way” experiments, in which the underlying idea is the same as in Young’s double-slit experiment. Due to its wave-like nature, a particle can be set up to travel along a quantum superposition of two different paths, resulting in an interference pattern. If however a “which-way” detector is employed to determine the particle’s path, the particle like behavior takes over and an interference pattern is no longer observed. These experiments have brought evidence that the loss of interference is not necessarily a consequence of the back action of a measurement process. Quantum complementarity is rather an inherent property of a system, enforced by quantum correlations. This manifestation of quantum mechanics enables random fusion energy distribution for cavity polaritons. Polaritons in micro-cavities are hybrid quasiparticles consisting of a superposition of cavity photons and two-dimensional collective electronic excitations (excitons) in an embedded quantum well. Owing to their mutual Coulomb interaction, pump polaritons generated by a resonant optical excitation can scatter resonantly into pairs of polaritons (signal and idler). In the low excitation limit, the polariton parametric scattering is a spontaneous process driven by vacuum-field fluctuations whereas, already at moderate excitation intensity, it displays self-stimulation. In either of these two cases where the fusion energy goes is directed by the luck of the draw and the randomness of the vacuum energy within the nano-cavity. Thermalization of fusion energy is all important in LENR because it preserves the structure of the NAE. If the energy produced by fusion was not moderated it would rapidly destroy the cavities that contained the reaction. This sometimes happens in LENR where water is present as the source of the dielectric. In this situation, the fusion energy produced by the reaction destroys the vessel of its creation and a crater erupts in the cathode of the LENR device.

-Original Message- From: Harry Veeder http://newenergytimes.com/v2/sr/WL/WLTheory.shtml Harry - let's count the number of miracles required for this to happen: quote Allan Widom and Lewis Larsen propose that, in condensed matter, local breakdown of the Born-Oppenheimer approximation occurs in homogeneous, many-body, collectively oscillating patches of protons, deuterons, or tritons found on surfaces of fully loaded metallic hydrides; Born-Oppenheimer breakdown enables a degree of electromagnetic coupling of surface proton/deuteron/triton oscillations with those of nearby surface plasmon polariton (SPP) electrons. Miracle 1 - SPPs couple with photons of light to become activated. There is little or no light in electrolysis LENR experiments - but some light exists in plasma glow or Mills reactions. If W-L want to cover electrolysis, then they should demonstrate the reality of light photons, which are absent. Blackbody radiation is not sufficient. Such coupling between collective oscillations creates local nuclear-strength electric fields in the vicinity of the patches. Miracle 2 - Nuclear strength is MeV. There is no evidence of MeV fields or even keV fields. These would be easy to document if they were present. Nuclear-strength electric fields produce x-ray radiation which is largely absent. SPP electrons bathed in such high fields increase their effective mass, thus becoming heavy electrons. Miracle 3 -Heavy electrons can apparently form near absolute zero, and then rarely - but there is no evidence of them forming at all at elevated temperature. Widom and Larsen propose that heavy SPP electrons can react directly with protons, deuterons, or tritons located in surface patches through an inverse beta decay process that results in simultaneous collective production of neutrons Miracle 4 - There is no known EC reaction with hydrogen - that is an absurd invention which is completely without precedent. Widom and Larsen propose two, or three neutrons, respectively, and a neutrino... Collectively produced neutrons are created ultra-cold; Miracle 5 - neutrinos are rarely captured in matter. This is even more outrageous than miracle 4. Widom and Larsen propose that such neutrons they have ultra-low momentum and extremely large quantum mechanical wavelengths and absorption cross-sections compared to typical neutrons at thermal energies. Miracle 6 - There is no evidence of this kind of neutron in all of physics - and ultracold neutrons, which are well-known, are not similar to the W-L concoction; but they should be if this proposal were to be taken seriously. Finally, Widom and Larsen propose that heavy SPP patch electrons are uniquely able to immediately convert almost any locally produced or incident gamma radiation directly into infrared heat energy, thus providing a form of built-in gamma shielding for LENR nuclear reactions. Miracle 7 - This is completely beyond belief. There is no evidence of gammas being converted to infrared in all of physics. Many observers who have followed LENR from the beginning are rightfully left in a state of what can only be called disgust at the shameless hucksterism (and attempted alteration) of established physics on display here.

RE: [Vo]:Re: CMNS: only a perfect LENR theory should attack other theories
Jed, For cell phone the maximum power from the mobile is given by the equilibrium between Uplink (Handset - base station) and Downlink (Base station - Handset). Hopefully, base stations have a better maximum power and also a better sensitivity for the receive path (around -110 dBm). The mobile sensitivity for the best one is -102 dBm. At the beginning of a call, the mobile is emitting at full power. Then the power is decreased over time if reception conditions are good at base station. The goal is to reduce interferences with other mobiles and safe the batteries. At the norm establishment (end 80s, early 90s) there was no health consideration. For GSM 2G 900Mhz Band, the maximum power is 2W (33 dBm) For GSM 2G 1800Mhz Band, the maximum power is 1W (30 dBm) For 3G, the maximum limit is 1W (not sure but around 1W) For CDMA and PCS (used in USA), the powers are in the same value range. For LENR point of view, if we want to make cell phone powered by LENR, there is no need to have a 2W LENR power device because: In call, the power is decreased over time. In standby mode (no call), consumption is very low. The best should have a battery charged by small LENR device of tenth of mW electric. Battery would be charged when the mobile is in standby mode (no call). Even with an efficiency of 5% to convert heat to electricity, only a 0.5W heat LENR device is far enough. 0.5W can be dissipated easily out of the cell phone. More generally, all nomad devices have a low power profile. They do not need for the generation of supercondensateurs for example, but LENR well.

Re: [Vo]:Re: CMNS: only a perfect LENR theory should attack other theories
The key mechanism of the WL theory is defined in a way to make it very hard or impossible to verify. The specification of the ultra-low energy neutron was engineered to make it virtually undetectable because it doesn’t move far from the nucleus before its immense nuclear absorption cross section results in its almost immediate incorporation into the nucleus immediately after its creation. The ultra-low energy neutron is a political windfall for LENR since it purportedly explains coulomb barrier penetration without the need to detect this particle. In my biased opinion, my plexciton theory is more experimentally practical. It is centered on an experimentally verified miracle called the hot spot. The hot spot in a lattice has been detected to concentrate input energy up to 500,000,000 times that into output energy levels. Other optimizations could push this concentration level into the trillions. The nice feature of my theory is that it can be experimentally verified. That means a lot. It seems natural to me that people interested in LENR should be interested in finding out more about these hot spots because such huge concentrations of energy are uncommon in nature especially since there is so much commonality between WL theory and Plexciton theory. NASA even calls their version of WL theory, Plexciton theory.

The discussion of theory we are witnessing is an indication of a deeper problem. Yes, CF is difficult to explain, but how we go about this discussion is important. The CMNS discussion group was designed to allow a select group of people to compare ideas in a safe and respectful way. On many occasions, this goal has not been achieved. On too many occasions, the discussion has been distracted by arrogance and hubris. These emotional reactions are expected because in many cases, we are competing for the same prize - the prize of explaining and applying the most important discovery of this century. But we are handicapped by a limited understanding of the phenomenon and generally by very little suitable training in the required general science. If we were discussing an accepted phenomenon, the arguments we would be allowed to make would be restrained by known laws. In the case of LENR, people feel free to ignore even the most basic laws of nature. Naturally, this approach generates outrage. Just how far from known behavior and accepted understanding a theory is permitted to deviate is an important question, but one that needs to be discussed with civility. Even so, the problem goes deeper. LENR is rejected by the people who determine when and how new ideas are developed. Why is this the case? I suggest this rejection occurs because the phenomenon involves a mixture of chemical and nuclear behavior. Both kinds of understanding are required to explain and apply the phenomenon. Most chemists have no training in nuclear physics and most physicists have no training in chemistry. Unfortunately, many physicists believe they understand all aspects of Nature. Because physicists generally control technological development of LENR, their collective opinions are important. I suggest the general rejection of LENR is the result of this combination of ignorance and arrogance, not because objective proof is lacking and not because it is called nuclear. Consequently, I see no solution to the general rejection until a device having a demonstrated level of commercial power has been achieved. Only then will the claim be accepted even by people who insist the phenomenon violates accepted theory. But, how can this goal be reached? At the present time, success in making LENR work results from luck because no method can be reproduced by everyone who makes the effort. In fact, even people who can make heat most of the time, still cannot control the process well enough for commercial application. Achieving this control is prevented by ignorance of the controlling variables. In other words, until the conditions required for the nuclear process to occur are identified and controlled, reliable success will not be possible. Understanding the nuclear process is not as important as knowing the required conditions because once the required conditions are created, the nuclear process occurs without further help. This important and essential insight is generally ignored when a theoretical understanding is attempted. Too many attempts either propose impossible conditions to precede the nuclear process or ignore the initiating conditions completely. I believe this failure to properly identify the unique and required conditions is the major flaw in the present theories. This understanding requires a knowledge of chemistry, not nuclear physics.

RE: [Vo]:Re: CMNS: only a perfect LENR theory should attack other theories
If the LENR mobile is coupled with a battery, then the battery will act as the main power supply when mobile is in call state. LENR power station should be seen here only has an embedded charger. In this condition, for the majority of the users, continuous tenth of mW is enough. In current available mobiles, it is not possible to have continuous call at 2W for a long period of time before batteries get empty. Nothing new for LENR here, because the majority of people are not ready to pay more to be able to call at 2W power 24h/24h. I'm not sure we want to have 10W heat power in our pockets. Fire hazards due to high temperature are here a main issue.

Again, this might be useful for someone lost in the woods on a cold winter night. You could turn on the emergency mode and leave it in your coat pocket.

Perhaps jealousy fuels some rejection, but in my case the problem is different. A person trained in science at the Ph.D. level has a basic understanding about how Nature behaves. The W-L theory violates this understanding in several important ways. These violations have no relationship to how skeptics view CF. The violations result from conflict with logic and basic behavior. When people trained in physics state that they think the theory is correct, a person has to wonder why. Did these people not obtain conventional training? Are these people unable to recognize flawed logic? These deficiencies are expected in untrained people, but how can they exist at NASA? Furthermore, when the challenges to the theory go unanswered, why would a serious scientist continue to claim it explains anything? A person has to question the effectiveness of the scientific method in this case. Ed - Jed

Eric, The website you cite has data for ultracold neutrons (energy ~300 neV.) Could any LENR experiment ever produce such cold neutrons? Even at just room temp, thermal neutrons possess energy of ~30 meV. Wouldn't ultracold neutrons be a tiny part of the Boltzman distribution? The thermal neutron cross section for Ni is quite high. Refer to: NGATLAS - Atlas of Neutron Capture Cross Sections http://www-nds.iaea.org/ngatlas2/ W-L electron capture may, or may not, occur, but AFAIK no one proposed that neutrons would be generated ultracold.

Eric, If LENR neutrons are indeed generated as proposed by W-L, almost all will be in the thermal range - quite a low momentum by fusion standards. I believe some experimenters have detected escaping neutrons. I do not know whether their measurements are valid. If they are, we still have to determine LENR neutron energy distribution. Given the graphs in the database - NGATLAS Atlas of Neutron Capture Cross Sections http://www-nds.iaea.org/ngatlas2/ - it seems reasonable to conjecture that most low-to-high thermal neutrons would not escape.
