Abstract

Sharp resonances in the photon-stimulated desorption (PSD) of ions from oxidized cerium using photon energies near the Ce 4d edge are reported. These resonances are due to autoionization from excited states arising from interaction of the Ce 4d and 4f levels. PSD spectra taken near the Ce 5p edge and valence photoemission studies near the Ce 4d edge allow examination of resonant-state decay channels leading to ion desorption. Comparison with optical-absorption data show the utility of PSD as a local probe for the determination of surface valency.
