Electron-Proton Fusion? | Physics Forums
www.physicsforums.com › threads › electron-protonApr 17, 2008 · A 'free' neutron is unstable with respect to beta decay, i.e. a neutron by itself will decay into a proton, beta and anti-neutrino, so the reverse action is unlikely. I suspect that electron capture may occur very rarely. EC does happen in certain proton-rich (neutron deficient) radionuclides, and typically it is a K-electron which is absorbed.
