THE CRYSTAL-FIELD STRENGTH PARAMETER AND THE MAXIMUM SPLITTING OF THE F-7(1) MANIFOLD OF THE EU3+ ION IN OXIDES

We examine, from both the experimental and theoretical point of view, the behavior of the maximum splitting Delta E, of the F-7(1) manifold of the Eu3+ ion as a function of the so-called crystal field strength parameter, N-v, in a series of oxides. In connection with the original theory that describes the relation between Delta E and N-v, a more consistent procedure to describe this relation is presented for the cases of small total angular momentum J. Good agreement is found between theory and experiment.
