The type of nuclear decay described here is beta decay.
plus or minus
Beta decay can either be a beta minus (β-) decay, where a neutron in the nucleus turns into a proton, releasing an electron and an antineutrino, or a beta plus (β+) decay, where a proton in the nucleus turns into a neutron, releasing a positron and a neutrino.
