Abstract
Energy levels, transition probabilities, oscillator strengths, and collision strengths have been calculated for transitions in Ne-like Ge. The data refer to a 241 fine-structure levels belonging to the configurations 1s2 2s2 2p5nl, 1s2 2s1 2p6nl (n = 3, 4, 5, 6; l = s, p, d, f, g and h), which have been calculated by the fully relativistic flexible atomic code (FAC). These data are used in the determination of the reduced population for the 241 fine structure levels and gain coefficients over a wide range of electron densities (from 2 × 10+20 to 4 × 10+22 cm-3) and at various electron plasma temperatures (650, 850, 1050, 1250, 1450, 1650, 1850) eV by using the MATLAB R2013a Computer program for solving simultaneous coupled rate equations. The reduced population for the 241 fine structure levels the gain coefficients for those transitions with positive population inversion factor are determined and plotted against the electron density.
Highlights
The concept for x-ray lasers went back to the 1965s, when it was based on the laser-produced plasmas by electron de-excitation having a promising interest science, which was first proposed by the Soviet scientists Gudzenko and Shelepin [1]
The possibility of laser emission from plasma of Ge XXIII ion via electron collisional pumping, in the XUV and soft X-ray spectral regions is investigated at different plasma temperatures and plasma electron densities
We present a comparison between our results and other theoretical transition probabilities for allowed E1 transitions for Ge XXIII in tables respectively
Summary
The concept for x-ray lasers went back to the 1965s, when it was based on the laser-produced plasmas by electron de-excitation having a promising interest science, which was first proposed by the Soviet scientists Gudzenko and Shelepin [1]. They thought that the short wavelength laser in the x-ray region of the electromagnetic spectrum needed a large energy gap which was sustained in the highly ionized ions. There exist in the literature some studies trying to develop high-efficiency X-ray laser with significant gain, for example, [3] [9] proposed the original mechanism for demonstrating X-ray lasing by resonant photo pumping.
