Electron capture



noun (physics)
1.
the transformation of an atomic nucleus in which an electron from the atom is spontaneously absorbed into the nucleus. A proton is changed into a neutron, thereby reducing the atomic number by 1. A neutrino is emitted. The process may be detected by the consequent emission of the characteristic X-rays of the resultant element Former name K-capture
