Paper Abstract

Stark line broadening for the n equals 5,4 to n equals 3 transitions of Li-like Al and for the n equals 5 to n equals 4 transitions of Li-like Mo and Na-like Rh in multicharged ion plasmas is considered. Line profiles are calculated with the quasi-static approximation for plasma ion broadening and the impact approximation for the electron broadening. The dependence of the linewidth of the Al XI 5f - 3d line on plasma temperature and density is investigated in the electron density and temperature domains typical for the conditions of recombination X-ray laser experiments. Calculated widths of the 5f - 3d line and the profiles of the Al XI 4f - 3d line are compared with experimental and other theoretical data. Tangible effect of Stark line broadening due to plasma ions for the 5g - 4f and 5f - 4d transitions of Li-like Mo and Na-like Rh is demonstrated at plasma conditions reasonable for theoretical investigation of a potential resonantly-photopumped X-ray laser schemes utilizing these transitions.
