Abstract
X-ray photoemission (XPS) measurements of wustite, (), show that the Fe () valence-band final states spread ∼10 eV below . This is much broader than previous claims based on the analysis of lower-energy (5-90 eV) photoemission spectra. Crystal-field-theory results, based on ab initio calculations, are consistent with the broader spectrum. Configuration interaction is found to have important consequences for the position and intensity of the XPS peaks.
