Radiative Auger effect

Radiative Auger effect is a decay channel of an inner-shell atomic vacancy state, in which an x-ray photon is emitted accompanying simultaneous promotion of an electron into either a bound or a continuum state. Thus the transition energy is shared between the photon and the electron. The effect was first observed by F. Bloch and P. A. Ross, with initial theoretical explanation by F. Bloch.
