This article presents an XPS study of Ce 3d emission spectra dominated by atomic multiplet effects in core level spectroscopy of rare earth compounds (Ce oxides). Core level spectroscopy has been used to study the electronic states of Ce 3d 5/2 and Ce 3d 3/2 levels in Ce 4+ and Ce 3+ states. The well‐resolved components of Ce 3d 5/2 and Ce 3d 3/2 spin‐orbit components, due to various final states (4f 0, 4f 1, 4f 2 configurations), were determined on 3d XPS spectra from commercial powders (CeO 2, CePO 4).
