N2 - A sequence of Cu2p XPS spectra has been measured for a CuO sample converted progressively to Cu2O under increasing temperatures of reduction (up to 1000°C). The experimental data are compared with a cluster configuration interaction model, especially in the case of CuO: we take into account the multiplet coupling between a Cu3d hole and a Cu2p core hole as well as the anisotropic hybridization between the 3d hole and 02p valence band holes. Within our model we are able to fit the experimental spectra of CuO and explain the tendency towards Cu2O.
