Well Robin, he did say the energy in his theory was shed as photons. There are only two possibilities for the source - electrons or nuclei. As far as I know, the nucleus sheds photons as gamma rays. AFAIK there is no apparent mechanism to shed photons from the nucleus at less energy than gamma ... but this is a weekend and I may not be thinking clearly. Tell me, is there any evidence in the literature of nuclei (not atoms but nuclei) shedding energy in quanta below gamma rays? Jones
