Fine-structure calculations of energy levels, oscillator strengths, and transition probabilities for sodium-like ions (Co XVII–Kr XXVI)

Abstract

We have calculated fine-structure energy levels, oscillator strengths and transition probabilities for transitions among the terms belonging to the 1s 22s 22p 6 ns ( 2S), 1s 22s 22p 6 np ( 2P), 1s 22s 22p 6 nd ( 2D) ( n = 3, 4, 5), and 1s 22s 22p 6 nf ( 2F) ( n = 4, 5) configurations. The calculations are based upon the general configuration-interaction code CIV3 of Hibbert which uses orthonormal orbitals of radial functions expressed as superpositions of normalized Slater-type orbitals. Our calculated values are compared with experimental and other theoretical results where a satisfactory agreement is found. We also report on some unpublished energy values and oscillator strengths.
