Abstract ：Atomic structure data and effective collision strengths for 1s 2 2s 2 2p 6 3s 2 3p 6 3d 10 and 54 fine-structure levels are contained in the configurations 1s 2 2s 2 2p 6 3s 2 3p 6 3d 9 4l (l =s, p, d, f ) for the nickel-like Ta ion. These data are used in the determination of the reduced population for the 55 fine structure levels over a wide range of electron densities (from 1021 to 1023 ) and at various electron plasma temperatures. The gain coefficients for those transitions with a positive population inversion factor are determined and plotted against the electron density.
