double beta decay The process in which two neutrons undergo beta decay simultaneously. (Beta decay involves a neutron transforming into a proton by emitting an electron and an antineutrino.) Of particular interest is the hypothetical process of neutrinoless double beta decay, in which the neutrons transform by emitting two electrons, but no antineutrinos.
