The electron spectrum of UF6 recorded in the gas phase

Abstract
Gas phase core and valence electron spectra from UF6, excited by AlKα monochromatized x rays, in the binding energy range 0–1000 eV are presented. It is shown that the AlKα excited valence electron spectrum can be used to reassign the highest occupied molecular orbital (HOMO) in UF6. Many‐body effects on the core levels are discussed and core level lifetimes are determined. The shift between solid phase and gas phase electron binding energies for core lines is used to discuss the U5 f population in UF6.
