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 or electron screening (antiscreening in the case of inverse photoemission) of the local electron excitations. Good agreement with experiment is obtained in all cases including the "anomalous" case of CeN.
