Electron capture

In radiobiology, electron capture refers to the nuclear decay process wherein a proton in the nucleus absorbs an orbiting electron and then converts it into a neutron. The electron absorbed is usually from the K or L electron shell. While the nuclear proton is converted into a neutron, an electron neutrino is simultaneously emitted. Synonyms: K-electron capture, K-capture, L-electron capture, L-capture.
