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were made are compared with other results in literature where a good agreement is found, we also report on some unpublished energy values and oscillator strengths.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.
