ABSTRACT: Level structure, oscillator strengths, transition
probabilities and radiative life times are evaluated for 1s2 2s2 2p63l,
4l, 5l (l = 0, 1, 2, 3, 4) states in sodium like Cu18+. The
calculations are carried out using COWAN code. The calculations
were made are compared with other results in literature where a good agreement
is found, we also report on some unpublished energy values and oscillator
strengths. Our results are used in the calculation of reduced population of 21
fine structure levels over a wide rang of electron density values (1018 to 1020) and at various electron plasma temperature. For those
transitions with positive population inversion factor, the gain coefficients are
evaluated and plotted against the electron density.
