Spectrum of Sn5+ in the Region 500–1300 Å

Atoms, 2017
The spectrum of tin, excited in a vacuum spark, was recorded in the region 500–1131 Å on a 6.65-m normal incidence spectrograph. The transitions between 4d85s, 4d86s, 4d85p and 4d85d excited configurations in Sn VI were studied.

Transition Rates for 3s3p^{2 4}P–3s3p4s ⁴P^o Transitions in Al i

Atoms, 2019
Fully relativistic calculations have been performed for two multiplets, 3 s 3 p 2 4 P and 3 s 3 p 4 s 4 P o , in Al i. Wave functions were obtained for all levels of these multiplets using the grasp programs.
