Abstract

Energy levels, oscillator strengths, and transition probabilities, for the 1s² 2s² 2p⁶, 2p⁵3l (l = 0, 1, 2), 2p⁵4l (l = 0, 1, 2, 3) states in Ni XIX and Cu XX are calculated using COWAN code. The Correlation and relativistic effects are considered. The calculations are compared with other results in the literature. A good agreement is found. We also report on some unpublished energy values.
