Abstract: | Atomic structure data and effective collision strengths for 1s2 2s2 2p6 3s2 3p63d10 and 54 fine-structure levels contained in the configurations 1s2 2s2 2p6 3s2 3p63d94l (l = s, p, d, f) for the nickel-like Gd 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 coefficient for those transitions with positive population inversion factor are determined and plotted against the electron density. |
