Abstract
The crystal field stabilization energy (CFSE) has been calculated for the fluorides, chlorides, bromides, and iodides of the rare earth elements (REE) in a field of cubic symmetry, taking account of spinorbital interaction. For the REE chlorides the calculations were also carried out without taking account of spin-orbital interaction. A relationship was found for the change in CFSE over the REE series. It was shown that the effect of the spin-orbital interaction is to shift the CFSE maximum to the first (Ce) and last (Yb) members of the REE series, and to decrease the absolute value of the CFSE. A particularly marked decrease in the value of the CFSE was observed for the middle members of each subgroup.
