This is one of those old-high school questions that never got answered (And the search mechanism here doesn't narrow on quotemarks)-- A neutron decays to a proton, electron, antineutrino ... But the highspeed escaping electron is a charge moving relative to (away from) the proton opposite charge and produces a photon (in the general sense; γ-ray; not much in the visible range) ... a noncyclic DC-pulse photon ... but,-- Do we have information on this DC-pulse-"photon"? It radiates symmetrically about the p-e axis so it's got a wave-only non-ray behavior ... but, it is energy-to-be-accounted radiating into space .... Do we have an account on this, DC-pulse γ-radiant "photon" from neutron decay? (And, What do high energy physicists call this "extra" energy,-- unmodeled zero point flux?) Ray.
