Theory of XPS and BIS Spectra in Ce₂O₃ and CeO₂

Abstract

The spectra of 3d photoemission, valence photoemission and BIS in Ce₂O₃ are analyzed theoretically by using the filled band Anderson model. The calculated spectra are in satisfactory agreement with experimental data by choosing appropriately the parameter values in the model. The characteristic features of these spectra are discussed in comparison with those of CeO₂, for which some new analysis is also made to obtain better agreement with experimental results.
