DIRECT CALCULATION OF ELECTRONIC RAMAN-SCATTERING INTENSITY FOR CE3+ IN CS2NACECL6

The direct calculation of electronic Raman scattering intensities is p resented in detail for four transitions from the electronic ground sta te to crystal field levels within the F-2(5/2) and F-2(7/2) multiplet terms of Ce3+ in the cubic host lattice Cs2NaCeCl6. The agreement with experiment is good without contributions from g-electron states, and the transition intensity pathways involve all of the d-electron states with mostly comparable contributions. The results are also similar to those from the conventional Judd-Ofelt-Axe theory since the effective baricentre approximation may be most valid for Ce3+ out of all the la nthanide ions.
