摘      要：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 *** data are used in the determination of the reduced population for the 55 fine structure levels over a wide range of electron densities(from 10^(21) to 10^(23))and at various electron plasma *** gain coefficients for those transitions with a positive population inversion factor are determined and plotted against the electron density.
