Excuse my grammar. English is not my native language.
Can energy and momentum be transferred from the new He4 to another nucleus at some distains? Energy can be transferred from one molecule to another threw a quantum mechanical mechanism. This occurs in photo synthesis there excitations can jump between electrons in different molecules. >From an older tread. http://www.mail-archive.com/vortex-l@eskimo.com/msg75294.html Maybe a similar phenomenon can occur between nucleus? This means the excitation from a He4 and momentum can be transferred to one or more receiver nucleus. These receiver nucleus must be a special nuclide suitable for receive the energy and have a mechanism to get rid of it. If several nucleus can get energy from one He4 it may radiate it as UV. If this not is possible I suggest that the receiver nucleus is a C12 how decay to 3 He4 as an reversed triple alpha. In absence of receiver nucleus there will be no reactions. But this did not explain the overcome of the coulomb barrier and why its not works in absence of receiver nucleus. I have heard that the conservation of momentum in LENR is commonly explained to "something" how would be like the Mössbauer effect. But I understand this not so easily to explain more exactly. TG
