Thus our theory well reproduce the Cu 2pand 3p-XPS. Our point is the effect of the anisotropic hybridization on the intraatomic multiplet coupling. In order to understand the high-energy spectra of the transition element compounds, at least, we must take into account the local electronic structure and the intraatomic multiplet coupling.

N2 - In this study, we discuss the multiplet structure observed in the Cu 2p- and 3p-XPS in La2CuO4, CuO and Cu dihalides using the single-site Anderson model. We take into account the multiplet coupling between a Cu 3d hole and a core hole, and the anisotropic hybridization between the 3d hole and O 2p valence band holes. As a result, we show that the multiplet structure is strongly affected by the anisotropic hybridization. We discuss the local electronic structures around the Cu atom by analyzing the deviation of the core-level XPS in these materials from the XPS in free Cu2+ ion.
