Mark, Horace In the original context of that posting, the problem is this. When Pd adsorbs a neutron and becomes activated, Pd (n,a) there should be a detectable secondary gamma.
BTW - this process would typically leave ruthenium, which is often seen in transmuted electrodes. In fact, years ago Passell found gammas, of an energy from the known ruthenium isotope emission spectrum, but that is one of those papers that was never replicated. Usually gammas are nearly absent in LENR, certainly less than the excess heat would indicate. That is why the suggestion was made that the UCN might not "act like a neutron" in the sense that even though the kinetic energy (which the UCN lacks) is small, in comparison to a typical ~1 MeV gamma, this could simply be an indication that it falls short of some unknown threshold, which still allows alpha emission, but at lower kinetic energy. Of course, in the sense of the virtual neutron, quasi-neutron, hydrex or so on, of the older theories - where the activating particle is stated as "not a real neutron" there is less of a problem ... ...except in lack of documentation ;-) Jones -----Original Message----- From: Mark Iverson Horace wrote: "I don't know why a neutron would not act like a neutron." Let me take a stab at that one... Perhaps because it's in a fully D-loaded palladium lattice, where other things aren't acting like they 'should'? ;-) Yeah, I know, that wasn't much help... -Mark -----Original Message----- From: Horace Heffner [mailto:hheff...@mtaonline.net] Sent: Thursday, December 10, 2009 6:27 PM To: vortex-l@eskimo.com Subject: Re: [Vo]:Falsifiability of cold neutrons in LENR On Dec 10, 2009, at 12:21 PM, Jones Beene wrote: > -----Original Message----- > From: Horace Heffner > >> That of course assumes the W&L claim that "neutron is thus absorbed >> within about ten nanometers" is valid.... > > As you go on to imply, that particular version is almost certainly not > valid, due to NA, and is probably "undergoing revision" as we speak > ... ;-) but of greater interest would be this: > > Is there a version of the broader UCN dynamic, using published > characteristics of the same instead of a tailor-made invention, which > stands up better to criticism and do involve NA ? > > This might go back many years.

I don't know why a neutron would not act like a neutron.
