Photoionization of Se2+ and S4+ ions using the screening constant per unit nuclear charge method
Autor: I. Sakho, M.T. Gning
Publikováno v: Results in Physics, Vol 55, Iss , Pp 107168- (2023)
Photoionization of Se2+ and S4+ ions are studied in this paper. Accurate resonance energies and quantum defects of the 4s4p2 (3P2, 1D2) 4 s → 4s4p2(2D5/2)np, and 4s24p (3P1, 3P2, 1D2) 4p → 4s24p(2P3/2)nd Rydberg transitions in Se2+ are reported.

Autor: Papa Amadou Lamine Diagne, Babou Diop, Fatou Ndoye, I. Sakho, Malick Sow, Momar Talla Gning
Publikováno v: International Journal of Advanced Research. 9:227-236
We report in this paper energy positions of Rydberg series from metastable state of Ca3+ ion.. Calculations are performed up to n = 20 using the Screening Constant by Unit Nuclear Charge (SCUNC). The present results compared wellwith the experimental
