Theory of Post-Collision-Interaction Effect in Resonant XES of La Compounds

Abstract

heory of the resonant 3d→2p X-ray emission spectroscopy (3d→2p RXES) for insulating La compounds is presented; the incident photon is tuned to resonate with the 2p→5d or continuum band (6s, 6d, ..., es, ed) transition and the X-ray emission due to the 3d→2p transition is observed. The spectra are calculated by using the impurity Anderson model and by applying the formula of a coherent second order optical process
