Proton emission — (also known as proton radioactivity) is a type of radioactive decay in which a proton is ejected from a nucleus. The decay of a proton rich nucleus A populates excited states of a daughter nucleus B by β+ emission or electron capture (EC). Those… … Wikipedia

Positron emission — is a type of beta decay, sometimes referred to as beta plus ( beta;+). In beta plus decay, a proton is converted, via the weak force, to a neutron, a positron (also known as the beta plus particle , the antimatter counterpart of an electron), and … Wikipedia
Electron capture — (sometimes called inverse beta decay) is a decay mode for isotopes that will occur when there are too many protons in the nucleus of an atom and insufficient energy to emit a positron; however, it continues to be a viable decay mode for… … Wikipedia
