ABSTRACT: Energy levels, transition probabilities and effective
collision strength for 1s2 2s2 2p6 3l, 4l,
5l (l = 0, 1, 2, 3, 4)
states of sodium like Fe are used in the determination of the reduced
populations for 21 fine structure levels over a wide rang of electron density
values (1018 to 1020 cm–3)
and at against electron plasma temperatures. Gain coefficients are evaluated
and plotted against the electron density.
