Nuclides that are imbalanced in their ratio of protons to neutrons undergo decay to correct the imbalance. Nuclei that are rich in protons relative to their number of neutrons can decay by conversion of a proton to a neutron, emitting a positron (\(^0_1e^+\)) and a neutrino (ν).Positrons are the antiparticles of electrons, …
