Abstract
SEVERAL authors1 have suggested that negative protons (p−) may be emitted from (β−-radioactive nuclei which emit a delayed neutron (n−0). (In our notations for the particles, the upper index refers to the charge, the lower one to the magnetic moment.) Some unsuccessful attempts2 at detection have been made. This suggestion has originated from the fact that the rest energies of the neutron and an electron ε− are together greater than that of p− by 1.826 MeV. It will be shown in this communication that the above suggestion is unfounded.
