Also observed, for charged pions only, is the very rare "pion beta decay " (with branching fraction of about 10 −8 ) into a neutral pion, an electron and an electron antineutrino (or for positive pions, a neutral pion, a positron, and electron neutrino). Source: Internet

Because lepton numbers must be conserved, one of the product neutrinos of muon decay must be a muon-type neutrino and the other an electron-type antineutrino (antimuon decay produces the corresponding antiparticles, as detailed below). Source: Internet

A schematic of the nucleus of an atom indicating radiation, the emission of a fast electron from the nucleus (the accompanying antineutrino is omitted). Source: Internet

For this reason, in early experiments a special reaction channel was chosen to facilitate the identification: the interaction of an antineutrino with one of the hydrogen nuclei in the water molecules. Source: Internet

In both processes, the intermediate emission of a virtual boson (which then decays to electron and antineutrino) is not shown. Source: Internet

Insert: in the decay of free neutron, a proton, an electron (negative beta ray), and an electron antineutrino are produced. Source: Internet
