摘要
We analyze the actinide 4f core X-ray photoemission spectra for actinide dioxide series, ThO2, UO2-BkO2, using the impurity Anderson model. Systematic variations of physical parameters, such as the charge transfer energy and the covalency hybridization strength, are investigated with the change of the actinide elements. We also calculate uranium 5d core X-ray absorption spectra (5d-XAS) of UO2 and other U compounds taking into account the effect of multiplet coupling. We discuss an important role of the interplay between the intra-atomic multiplet coupling and the inter-atomic hybridization on the 5d-XAS.
