摘要：

The density of the 4f states in all metallic rare earths has been studied with bremsstrahlung isochromat spectroscopy (BIS) and x-ray photoemission spectroscopy (XPS). The final-state multiplet structures of the 4f14-n and 4fn configurations observed by BIS and XPS, respectively, are closely related. The elements showing interconfiguration fluctuations are found to have one 4f level in the immediate vicinity of the Fermi level. Correlation energies are extracted directly from the spectra and compared with recent theoretical calculations. © 1978 The American Physical Society.
