The band structure of UO 2: An angle resolved and resonant photoemission study

Abstract

A detailed study of angle resolved photoemission of UO 2 〈100〉 in the normal emission configuration is presented. The results are compared with a semirelativistic linearized augmented plane wave (LAPW) band calculation with the actual calculated empty bands used in the data reduction. Excellent agreement is found with calculations both for filled states as well as critical points in the empty states with no adjustment of bands, f-p Hybridization is found at the leading edge of the valence band and not at the bottom of the valence band, p-d Hybridization is found throughout the valence bands.
