摘要

The energy displacement of non-degeneratedelectronic ~(2S+1)L_J levels, (J=0 or 1/2), along thenephelauxetic scale of a rare earth ion can be easily connected withthe evolution of the barycenter position of different ~(2S+1)L_Jlevels of 4f" ground configurations. Linear slopes are obtained andpresented for different crystal field (cf) levels for Nd~(3+), Pr~(3+)and Eu~(3+), corresponding to the 4f~2, 4f~3 and 4f~6configurations, respectively. A ~(2S+1)L_J level barycenterpositioned out of slope suggests incorrect assignment of the level.Moreover, some missing Stark components of a given ~(2S+1)L_Jlevel can be correctly extrapolated on the basis of thecorresponding barycenter deduced from the slope. It is particularlyevident in the case of low J values. The example of the ~2P_(3/2)level for Nd~(3+) doped Ca_4GdO(BO_3)_3 (GdCOB) crystal isgiven as an illustration.
