The Ce 3 d and 4 d core X-ray photoemission spectra (3 d and 4 d XPS) of Ce compounds are studied based on the impurity Anderson model considering atomic multiplets arising from electron-electron interaction. We make a consistent analysis of 3 d and 4 d XPS of trivalent Ce compounds CeF 3 , CeCl 3 and Ce 2 O 3 , which can only be made by considering the atomic multiplets. We also apply the approach to the interpretation of the spectra of mixed valent Ce systems Ce–Ni compounds and CeO 2 . We show that the analysis of the multiplet structure gives information about many-body electronic states of the system.
