This was a wandering mind tying. 8^) It should say: "I think this is a misunderstanding of what the 20.3 keV represents. It does not represent the Q of the reaction. It represents an (experimental) upper limit on the kinetic energy the 4He obtains from the reaction.
As I wrote, yes, this was my understanding. Not Q at all.
This is not at all a surprising result if, as I and various others have predicted, the D+D -> 4He branch produces most of its enthalpy in the form of low energy GAMMAS (photons) with the possibility one or two low energy betas as well."
Okay, please describe how that would work, and what would be predicted for the alpha energies. More than one gamma? How? Simultaneously? And why would it happen that way?
