Description

Ultraviolet and x-ray-photoelectron spectra of core and valence levels in U metal, UN, UO2, Th, and ThN have been obtained. These spectra demonstrate the existence in uranium nitride of a sharp band of f states (containing 2.2 +- 0.5 electrons) at the Fermi level. The anomalously broad 4f core levels in UN are discussed in terms of several possible energy-loss mechanisms, including configuration interaction and alternating valency. No change is seen in the density of f states of UN on cooling through the antiferromagnetic transition
