Inverse beta decay process involving a muon antineutrino.

Inverse beta decay is a somewhat vague term referring to one of several processes related to beta decay.

Inverse beta decay originally referred to the process ${\bar {\nu }}_{e}+p\to e^{+}+n$ ,

(electron antineutrino scattering off a proton into a positron and a neutron) in which the existence of the antineutrino was decisively verified in the Cowan–Reines neutrino experiment. Understanding this process is important to our understanding of the mechanism of a supernova explosion.

Inverse beta decay may also sometimes refer to the process $e^{-}+p\to \nu _{e}+n$ normally called electron capture.
