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also report on some unpublished energy values.
