e·lec·tron cap·ture

a mode of radioactive disintegration, in which an orbital electron, usually from the K shell, is captured by the nucleus, converting a proton into a neutron with ejection of a neutrino and emission of a gamma ray, and emission of characteristic x-rays as the missing K-shell electron is replaced.
