High gain predictions for Ni-like Gd ion

Abdelaziz, W. S., "High gain predictions for Ni-like Gd ion", Optics Communications, vol. 284, issue 12, pp. 2859-2862, 2011.


Atomic structure data and effective collision strengths for 1s22s22p63s23p6 3d10and 54 ?ne-structure levels contained in the con?gurations 1s22s22p63s23p63d9 4l (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 ?ne structure levels over a wide range of electron densities (from 1021 to 1023) and at various electron plasma temperatures. The gain coef?cient for those transitions with positive population inversion factor are determined and plotted against the electron density.
