Evidence for a "Radiative Auger Effect" in X-Ray Photon Emission

Abstract

A broad x-ray emission structure with several maxima has been found on the low-energy side of the $K{\alpha }_1{\alpha }_2$ line in Mg, Al, Si, and S. It is interpreted as a radiative $K\to L^2$ transition resulting in the simultaneous emission of a photon and an $L$-shell electron.
