Theory of the Radiative Auger Effect
Abstract
The probability of simultaneous emission of an x-ray photon and an electron is considered. It is shown that this process can occur as a consequence of the change in the average potential acting on the electrons when the x-ray hole is moving from an inner to an outer shell (shake-off) and as a consequence of interaction between single- and double-hole configurations in the final state. Relative shake-off probabilities of K-->L2, K-->M2, and L2,3-->M1M2,3 transitions are calculated for F-, Ne, Na+, Cl-, Ar, and K+ from Bagus's self-consistent-field wave functions of single-hole x-ray states. The relative probability of K-->L2 and K-->M2 transitions is estimated for the rest of the atoms in the range 9<=Z<=22. The estimated K-->L2 and K-->M2 probabilities are of the same order of magnitude as the observed probabilities. However, for low Z, they overestimate the observed probabilities, which may be because the shake-off calculations do not account properly for the interaction between single- and double-hole configurations in the final state.
