Abstract

Resonance photoemission spectroscopy was performed on (Formula presented) at the Ce (Formula presented) and (Formula presented) core thresholds. We also obtained angle-dependent (Formula presented) resonant spectra. Surface and bulk (Formula presented) spectra were derived using differences both in the angle-dependent spectra and in the resonant spectra at the two different thresholds. The surface and bulk spectra are different depending on the derivation methods, and the spectra derived from the angle dependence are more consistent with theoretical spectra using the Gunnarsson-Schönhammer method of the Anderson impurity model, which implies that the two resonant spectra may reflect different (Formula presented)-removal spectra.
