Evidence of 4f photoemission satellites in cerium compounds
Abstract
Experiments on CeP, CeAs, and CeBi have revealed two 4f-derived photoemission features at binding energies of 0.6 eV [FWHM (full width at half maximum)0.7 eV] and 3.0-3.1 eV (FWHM 1.0 eV) due to competing Ce 4f photoionization channels. The relative intensity of the two spectral features changes by 10 from CeP to CeBi. These findings indicate strong f-p hybridization and force a reevaluation of previous 4f binding energies in Ce compounds. © 1981 The American Physical Society.
