摘要：

The Yb 3d core-level photoemission spectra of trivalent YbAs, mixed-valence YbAl3, and divalent YbPb3 were measured with a Si K x-ray source. Significant intensities of divalent peaks were observed even for trivalent YbAs and mixed-valence YbAl3. This is probably due to the divalent surface layers, which makes difficult the estimation of the 4f hybridization strength from the 3d core-level spectra. The 4d core-level and the 4f spectra are consistent with this interpretation. © 1990 The American Physical Society.
