Description
Simple ab initio model perturbation calculations of the crystal-field parameters for the U4+ ion in UO2 crystals are reported. The crystal-field parameters obtained, B04 = -7130 cm-1 and B06 = 2890 cm-1, turn out to be much lower in value, particularly the first one, than those usually assumed for this compound. They are found, however, to agree with new spectroscopic data and recent inelastic neutron scattering measurements. (orig.)
