If you are implying they are quarks, then no. Quarks do not come
"unglued" even at near TeV energies. They are always in at least
pairs (mesons) or triads (hadrons).
That is not implied, of course, and no one else seems to have had
the temerity to make a big case for this implication to date,
but ... let me
ask ... how else (aside from Theology) does one find three distinct
components to a single entity?
SPAWAR proposed the triple tracks were from the three alpha producing
reaction:
n + C12 + (9 MeV minimum kinetic energy for subsequent triple
tracks seen) --> 3 He
This was logical because that is commonly seen in CR-39 when high
energy neutrons are present. SPAWAR suggests the neutrons come from:
D + T --> 4He (3.5 MeV) + n (14.1 MeV)
Here is an article relating to T2O + D2O electrolysis with some rare
(8 +-4 counts per second) 10 MeV plus neutrons found: Quote:

The above summary was taken from Dieter Britz's site:
http://www.chem.au.dk/~db/fusion/alpha_R
The above experiment provides a solid indication of a nominal amount
of D-T fusion even though there is no indication whatsoever that
proper lattice conditions for cold fusion were established. If
repeatable, that is a landmark achievement because it proves fusion
from chemical conditions. Hopefully with what is known today the
results can be greatly improved.
However, the *low counts* even at 50-50 mix may also be an indication
that the SPAWAR tracks are *not* from high energy neutrons. The
SPAWAR lattice has to have a negligible amount of tritium, created by
cold fusion itself, and the tritium branch is highly suppressed.
Even a slight doping of the electrolyte with tritium should multiply
the neutron counts by orders of magnitude - *if* the high energy
neutrons are from D-T reactions.
Do a locate on "triple" in:
http://www.mtaonline.net/~hheffner/CFnuclearReactions.pdf
where you can see I proposed the knock on reaction:
lambda0 + p --> p + p + pi-
as a possible alternative reaction to the 12C(n,n’)3α SPAWAR
reaction.
The SPAWAR data does indeed seem to suggest high energy neutrons from
a DT reaction. The source of the tritium in SPAWAR experiments
logically can be expected to be DD fusion, and thus of a low
probability because the concentration of tritium (or possibly some
form of tritium precursor) is very low. It should be no surprise that
tritium can be produced in small quantities via cold fusion reactions.
The conclusion of the Boss et al article implies the need for
repeating exactly the same experiment using D2O + T2O (actually just
a trace amount of TDO) instead of just D2O. If the flux of high
energy neutrons does not increase, then the conclusion is suspect.
Otherwise, this will provide some confirmation of the Boss et al
conclusion. More importantly, if high energy neutrons can be
reliably produced using the more sophisticated, successful, and
controlled protocol as used by Boss et al, this could provide a solid
starting point for narrowing down the underlying physics. A tritium
atom does not differ significantly from a deuterium atom with respect
to the Coulomb barrier. Whatever mechanism permits deuterium to
defeat the Coulomb barrier should also permit tritium to do so
also. The difference may be that the cross section is larger and
the signature unmistakable and highly repeatable.
Though the use of tritium can only be done in the US by licensed
labs, and practical devices would preferably be deuterium only,
tritium doping experiments may provide a necessary step in the
progress toward practical devices.
Because the tritium available in the SPAWAR D loaded cathode must be
nominal in the extreme, and likely primarily there due to DD fusion,
the cross section for lattice based DT fusion has to be enormous,
much larger than 100 times the DD cross section (if cross section is
even a valid concept for lattice assisted fusion) to support the DT
hypothesis. The tritium must be used up very quickly after forming.
Perhaps lattice half-life (LHL) would be a better concept than cross
section, in loaded lattices, because the term cross section pre-
supposes a collision, kinetic interaction, hot fusion. LHL is a term
which would have meaning only in the context of a specific degree of
lattice loading. I expect when highly confirmed theories of LENR are
available such a term could be defined including a formula component
descriptive of lattice loading conditions.
If Boss et al are correct in their deductions of the source of high
energy neutrons, then a huge breakthrough is at hand. If
contradictions are found in the D-T hypothesis, or unexpected energy
spectra are identified, it does not necessarily mean that increasing
the D-T reaction rate is not useful, and it does not mean huge
benefits cannot be obtained by increasing the miniscule T
concentration even by a factor of a few orders of magnitude. Tritium
doping should be useful for analyzing and improving any CF protocol,
especially those capable of producing excess heat.
Lattice assisted DD fusion nearly eliminates the neutron forming
branch, but there is no reason to believe that lattice assisted D-T
fusion will nearly fully suppress neutron generation. In the case of
D-D fusion there are three branch possibilities, two of which create
no neutrons. Given that a lattice assisted D-D fusion nucleus is not
created by energetic kinetic action, but rather by electron
catalysis, it should be no surprise the branch producing the highest
energy is highly favored, namely D+D->He4, and the other feasible
branches highly suppressed. There is no probable similar
alternative branch for the D-T or T-T fusion that creates no
neutrons. All the tritium fusion reactions create neutrons. Tritium
doping is thus extremely useful for diagnosing whether excess heat is
from actual fusion or from some other source.
Tritium doping provides a window into what is happening in the
lattice, via the energy spectrum of the resulting high energy
neutrons. It certainly is not logical that D-D fusion can occur in a
lattice assisted manner and yet D-T or even T-T fusion can not. The
Coulomb barrier is the same. Tritium likely provides a large
tunneling target because the D-T hot fusion cross section is large.
If D-T fusion is indeed in fact occurring in the lattice, as Boss et
al hypothesize, it is therefore unreasonable to not expect neutron
generation. However, the mechanism of fusion in the lattice is
energetically different from hot fusion, and I would expect the
neutron energy to differ. In fact I would expect high energy
neutrons to exhibit a spectrum of kinetic energies for reasons I have
posted here and published regarding the "Deflation Fusion" scenario.
Under that or any electron catalysis scenario, I would in fact not
expect 14 MeV neutrons from D-T fusion reactions, while a significant
number above 6 MeV could be expected, with a fuzzy peak.
Tritium doping should (a) produce highly repeatable and
incontrovertible proof of nuclear reactions and (b) provide an
effective means of quickly measuring reaction rates while dynamically
varying experimental conditions.
If tritium doping is used, then lattice assisted fusion should also
result in the p-T reactions: T(p,n)3He and T(p,gamma)4He. The latter
reaction might be considered as unlikely as D(D,gamma)4He is
conventionally considered to be due to initial kinetic energy
requirements and lack of an inertial pair to distribute resulting
kinetic energy. However, under the deflation fusion scenario, or some
other electron catalyzed fusion scenarios, the nucleus enclosed
electron provides a means of releasing radiant energy and momentum in
small increments, and high initial energies are not required to
trigger the reaction. The T(p,n)3He reaction requires from 1 to 5
MeV kinetic energy to pull off as hot fusion. Given that electron
catalyzed fusion reactions result in highly de-energized nuclei, and
the resulting radiant energy is largely from the vacuum, it may be
that T(p,n)3He is feasible as a cold electron catalyzed reaction. If
lattice assisted D-T reactions can occur with much higher observed
frequencies than expected for the reactant concentrations, as
possibly indicated in SPAWAR results, then p-T reactions may also
have a higher frequency than expected for the reactant
concentrations. Protium from ambient humidity can be expected to
contaminate D2O cells, especially long running open cells. This
could account for highly variable neutron production over long run
times. In a D2O experiment an initial period is required to build up
trace T and another period is required to build up p. The SPAWAR
CR-39 could possibly have 3He tracks resulting from T(p,n)3He or D
(D,n)3He reactions, as well as neutron reaction induced tracks. All
this indicates that tritium doping of even all protium based
experiments may not provide adequate controls.
If lattice fusion reactions should produce high energy particles,
especially third particle Bose condensate stimulation based reactions
(as opposed to low energy electron catalyzed reactions) produce high
energy particles, and conditions for producing many small Bose
condensates exist, then it is clear that unexpected chain reactions
can result. The D(D,n)3He reaction, for example, produces two
particles for each reaction. It is thus important to diagnose
exactly what conditions in the lattice are producing energetic
results in what proportions. It seems to me feasible that both 3rd
particle seeded Bose condensate collapse mechanisms as well as
electron catalyzed fusion mechanisms can be at work in differing
proportions in differing experiments, or a given experiment at
differing times. What has been missing is a means to diagnose these
kinds of things. Tritium doping may well lead to such a diagnostic
capability.
Lastly, I should mention x-ray stimulation, because I think it has
the greatest chances of robust effects. Deflation fusion is driven
by (1) creating the deflated state with high probability, and (2)
maximizing tunneling rate in the lattice. X-ray stimulation can be
used to increase the latter. X-ray stimulation might be combined with
radioisotpe lattice doping. Impurities like B, SI, and C, are known
to create interstitial locations wherein "trapped hydrogen can jump
between a limited number of sites without diffusing away from the
trapping atom." (see Topics in Applied Physics, Volume 73, Hydrogen
in Metals II, p. 76.) Also worthy of note is the fact (noted on p.
77), regarding hydrogen motion between double well potentials between
two nearest neighbor tetrahedral sites, that tunneling is the
dominating transport mechanism, with coherent tunneling occurring at
less than 10 K, and incoherent tunneling occurring above a
temperature of 10 K. Further, "tunneling dynamics is strongly
affected by a nonadiabatic interaction of the hydrogen with the
conduction electrons." Given the existence of such trapping sites,
it seems to me beneficial to find a way to stimulate a high tunneling
rate, using a method not involving diffusion, but rather conduction
band electron stimulation. The best method of doing this seems to me
to use coherent x-rays, probably from a wiggler, as that would be
capable of producing a volume effect. Even if effective at producing
fusion the problem then might be too high a requirement for energy
in. It may be that a resonant ultrasound vibration could be set up to
stimulate tunneling without excessive diffusion. Phonons should in my
opinion stimulate significant conduction band - partial orbital state
changes for ionically bound electrons. This kind of stimulation
would also avoid the helium blocking of diffusion problem, as fusion
would be triggered throughout the lattice without the need for other
than the initial loading diffusion. This then would provide a volume
effect instead of a surface effect. It also would enable loading at a
high temperature and cooling a bit to increase orbital stressing
without worries about reduced diffusion rates. The problem of
course is finding the right mix of all these things.
