Resonance in the photon-stimulated desportion (PSD) spectra of La, Ce, and Er oxides are reported at photon energies near the La(4d), Ce(4d), and Er(3d) edges. These resonances, also seen in soft x-ray absorption (SXA), arise from excitations of d electrons to the 4f shell. Comparisons of SXA and PSD show how PSD can be used to determine surface valency. ESD data from Ce and Er oxides is used to establish the importance of the 5p level in the electronic pathways which lead to desorption.
