Theory of XPS and BIS Spectra in Ce₂O₃and CeO₂

Abstract

The spectra of 3 d photoemission, valence photoemission and BIS in Ce 2 O 3 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 CeO 2 , for which some new analysis is also made to obtain better agreement with experimental results.
