Systematic calculation of seven times ionized cesium

Abstract

The Theoretical calculations were performed by using Cowan’s computer code. The ground configuration 4d105S2 and ground most level 1S0 of cesium seven (Cs viii) time ionized atom. Incorporating other interacting even parity configurations even parity configurations 5 snd (n=6,7), 5sns (n=7,8), 5p2, 5sng (n=6,7) 5p4f, 5d2, 6p2, 5p6p, 6s2, 5d6s, and odd parity configurations, 5snp (n=6,7), 4d95s25p, 4d95s24f, 5snf (n=4,5), 5p5d, 5s6p, 5p6s, 5p5g, 5d4f, 6p6s, 6p6s, 6p6d and 4f6s. The initial energy parameter scaling applied for Eav and ζ at 100% of the HFR values and Fk, Gk and Rk at 85% of the HFR values. All The reported energy levels were taken from NIST ASD levels list. The levels were used to run the least square fitted (LSF). This allowed adjusting the energy to the real values and hence a better prediction was achieved.The Theoretical calculations were performed by using Cowan’s computer code.
