Abstract

The energy levels, oscillator strengths, and E1 transition probabilities have been calculated for calcium-like ions with Z = 22 − 30 (excluding iron). The calculations have been executed using the CIV3 and LANL codes for a set of configuration arrays including 63 fine structure levels (in this paper we mentioned for examples about 40 energy levels) belonging to 3p63d2 and 3p63d4l configurations, where l = s, p, d, f. The correlations up to 6l orbitals are included to optimize the wave functions generated by the CIV3 code. In spite of the complexity of the Ca sequence, the present results are in fairly good agreement with the experimental and theoretical data available in the literature. The present study provides calculations of various atomic structure data which are necessary for many fields of researches and applications, especially in the astrophysics and plasma diagnostics.
