R. Gayasov et Yn. Joshi, TRANSITIONS FROM THE CONFIGURATIONS INVOLVING 4F-ELECTRONS IN CS-IX LA-XI AND CS-XI CE-XIV SPECTRA, Journal of physics. B, Atomic molecular and optical physics (Print), 31(18), 1998, pp. 705-709
The 4d(9)-4d(8)4f transitions in Rh I-like ions from Cs XI to Ce XIV h
ave been identified. Two lines, the 4d(10)5s S-2-4d(9)5s4f P-2 transit
ions, in Cs Ix to LaXI have also been identified. In the La rx spectru
m the 4d(10)4f F-2 and 4d(10)8p( 2)P levels have also been established
. Predictions for the corresponding transitions in Xe VIII and Xe X ar
e also given.
