Abstract

The origin of the two-peak photoemission and inverse-photoemission spectra in Ce and its pnictide compounds (CeP, CeSb, and CeN) is investigated with ab initio total-energy self-consistent supercell energy-band and molecular-cluster approaches to represent physically the competing mechanisms involved in d or f electron screening (antiscreening in the case of inverse photoemission) of the local 4f electron excitations. Good agreement with experiment is obtained in all cases including the "anomalous" case of CeN.
