Abstract

The 4d-4f resonant photoemission spectra for Ce₂O₃ and γ-Ce are analyzed theoretically by using the impurity Anderson model. It is shown that the resonant photoemission can be analyzed consistently with the other photoemission and BIS spectra which were analyzed previously. The difference in the resonance behavior between Ce₂O₃ and γ-Ce is ascribed to the difference in the mixing between f² and f³ configurations in the intermediate state, as well as that between f⁰ and f¹ configurations in the final state. Some discussion is given on the separation of the 4f-derived emission from other symmetry components.
