While the presence of a ~17 MeV decay path, from excited 4He could explain aspects of the D+D => 4He of CF by avoiding both the fragmentation and lack of >20 MeV photons from this fusion, there are other problems with this solution. The main problem is the lack of 511 keV annihilation radiation from the positrons posited. An associated problem is the quantity of lepton energy, required to produce the observed excess heat, would mean vast quantities of the positrons to produce said radiation.
On the other hand, there are arguments for why such a decay path could be possible for CF, if we consider the two ~100 MeV deep-orbit electrons created in the fusing of the deuterium pair. A better test of the X17 hypothesis might be the photo-excitation to the first excited states of 4He. Present results of such work yield the dominant proton + tritium fragmentation of those excitations. However, it is unlikely that such experiments sought, or were even equipped to selectively detect and identify, the energetic leptons proposed for the X17 model Andrew _ _ _ On Tue, Nov 26, 2019 at 9:56 AM Jones Beene <[email protected]> wrote: > As fate would have it, the identity of a "fifth force" of nature is > becoming closely tied to LENR and the findings of Holmlid about proton > annihilation. > > Five years ago in Hungary, Attila Krasznahorkay at the Hungarian Inst.for > Nuclear Research presented evidence for a previously undescribed light > boson (17 MeV) - which is about 34 times heavier than the electron.
