This may be true, as far as it goes, but it still seems to missing the forest for the trees. Every "stop" or elastic collision is a high energy transfer event, and the thermodynamics of this kind of cascade are well known for fifty years - and will average to about one MeV or less in gamma radiation per elastic collision. The combined 24-50 collisions or more will create a gigantic and easily detected radiation signature that would be impossible to hide, if it was there. Even if the (Peter Hagelstein et al) "magic phonon cascade" hypothesis were operable, and there is zero evidence for that hypothesis in all of physics, it could not be an "absolute phenomenon" that would eliminate the significant probability of the normal and expected situation, and some of the signature should still be there. It is not there, in a significant way. ERGO there are few 24 MeV alphas, and probably no TSC - at least not in the way it has been presented thus far. ... there is helium, so all this is saying is that for the large amount of excess heat seen, it cannot be attributed to high energy alphas.
