Inverse beta decay

This article is about capture of an antineutrino. For capture of an electron, see electron capture.

In nuclear and particle physics, inverse beta decay, commonly abbreviated to IBD,[1] is a nuclear reaction involving an electron antineutrino scattering off a proton, creating a positron and a neutron. This process is commonly used in the detection of electron antineutrinos in neutrino detectors, such as the first detection of antineutrinos in the Cowan–Reines neutrino experiment, or in neutrino experiments such as KamLAND and Borexino. It is an essential process to experiments involving low-energy neutrinos (< 60 MeV)[2] such as those studying neutrino oscillation,[2] reactor neutrinos, sterile neutrinos, and geoneutrinos.[3]
