Thus, we have a gap of four orders of magnitude. However, beta decay is due to the weak interaction. We can not simply use standard physics inside the nucleus. While I can imagine that additional energy opens other some channels, I don't believe that weak interaction requires an activation energy. However, this is far beyond my field. So you should check that. | |

There may be a flaw in my reasoning here but I was thinking that the positive electric charge could somehow help "draw out" an electron from inside a neutron (make the probability of decay higher) if the nucleus was hit with enough energy for the mass-energy equivalent of an electron. | |
