• Theory of the La 2p3d3d resonant Auger electron spectroscopy for insulating La-compounds is presented for the process that the incident photon is tuned to resonate with 2p→5d or the continuum (6s, 6d,…εs, εd) transition and the Auger electron due to the 2p3d3d Auger transition is observed. The theory is based on the impurity Anderson model that takes into account the hybridization of the La 4f-level with the anion valence band and also the effect of the core hole potential for the 4f- and 5d-electrons. It is shown that the core exciton effect due to the Coulomb attraction between the core holes and the photoexcited 5d-electron plays an important role in deter-mining the spectral features of the Auger transition.
