The electron-positron pair production and the β+-transformation of atomic nuclei require the same minimum energy of 1,022MeV.

The competing processes of the β+-transformation of an atomic nucleus is the capture of an electron.

The conclusion has to be drawn that at the positron-emission initially take place a pair production. The electron is captured and the structural superfluous positron is emitted.

Subsequent remark: "Neutrinos" are of no significance with my initial question. It is Kåre Olaussens attempt to talk down my question by distraction on this side stage. It has to be explained how the "neutrinos" were focused on his uploaded picture. If the "neutrinos" would interact with the detector or sensor the whole sensor would be even exposed. Also his response that the transmuted nuclei must only have a mass 0.511 MeV/c2 lower than its parent is wrong.
