Abstract

The occupied and empty electronic states of the insulator CeO2 have been studied by high-energy spectroscopies. The outer-level spectra reveal empty localized 4f1 states within the band gap. The core-level spectra display different final-state populations of the 4f localized states which are well predicted by a many-body calculation taking into account the presence of f-symmetry admixture in the valence band. A mixed valence can be definitely excluded in CeO2.
