Abstract
The valence transition of trivalent γ-Ce to tetravalent cerium with oxidation has been studied with Soft X-ray Appearance Potential Spectroscopy (SXAPS). The spectra are discussed within the framework of the Gunnarsson-Schönhammer-model. The inclusion of multiplet effects allows the determination of the 4f-count of cerium in CeO2.
