Energy Levels and Dipole Oscillator Strengths in the Magnesium Isoelectronic Sequence

摘要

Energy levels of the 1S sup 2 2S sup 2 2p sup 6 3sns ( sup 3 S, sup 1 S); n=4-7, 1S sup 2 2S sup 2 2p sup 6 3Snp( sup 3 p, sup 1 p); n=3-7, 1S sup 2 2S sup 2 2p sup 6 3Snd( sup 3 D, sup 1 D); n=3-7 and 1S sup 2 2S sup 2 2p sup 6 3Snf( sup 3 F, sup 1 F); n=4-7 excited states of MgI sequence are calculated using single configuration Hartree-Fock method. Hence the results are used in evaluating dipole oscillator strengths for the 3Sns( sup 1 S)-3Smp( sup 1 p); (n,m=3-7), 3Snp( sup 1 p)-3Smd( sup 1 D); (n=4-7, m=3-6) single transitions and the 3Sns( sup 3 S)-3Smp( sup 3 p); (n=4-7, m=3-7), 3Snp( sup 3 p)-3Smd( sup 3 D); (n=4-7, m=3-6) triplet transitions in the isoelectronic sequence. The results are comparable with the experimental values. Lifetimes of the upper 3Sns( sup 3 S, sup 1 S); (n=4-7) and 3Snp( sup 3 p, sup 1 p); (n=3-7) excited states are obtained and compared with the available experimental data. 22 references, 3 figures, 12 tables.
