Once, in about every 10^20 reversible fusion events, there is a beta decay in the short time before the reversal can complete.
It is one of the rarest events in physics - but without it, our sun produces no heat. On earth, because of this rarity - an experimenter could run an LENR cell for a thousand years and never see a single proton-proton fusion proceed to deuterium From: Harry Veeder It seems a bit more logical to suggest that the lack of gammas can be better explained by the lack of the kind of nuclear reaction that produces gammas. The most prevalent nuclear reaction in the Universe, reversible proton fusion, produces no gammas. Shouldn't we be taking a closer look at RPF? Wikipedia says proton-proton fusion produces a neutrino and a positron. http://en.wikipedia.org/wiki/Proton%E2%80%93proton_chain_reaction Won't this result in an electron-positron anihilation and two gamma rays? http://en.wikipedia.org/wiki/Electron%E2%80%93positron_annihilation Harry
