We have performed an x-ray photoemission (XPS) experiment using tunable x rays in the photon-energy range between 1500 and 3000 eV. The deep metal 3p core-level spectra of the tetravalent oxides MO2, M=Ce, Pr, Tb, and Hf have been measured. The results show that the configuration interaction between localized 4fn and 4fn+1L configuration in the initial state gives final-state peaks 3p4fn, 3p4fn+1L, and 3p4fn+2L2. The final states of Ce 3p core levels of CeO2 have been calculated by the many-body theory in the frame of the filled-band Anderson model.
