Stark broadening of Xe viii spectral lines [PDF]
Monthly Notices of the Royal Astronomical Society, 2015 Stark broadening parameters have been calculated for 60 spectral lines of Xe VIII, for broadening by electron, proton, and He III impacts. For calculations, the semiclassical perturbation approach in the impact approximation has been used. The widths and shifts are provided for temperatures from 20 000 K to 500 000 K and for an electron density of 10 ...

Stark broadening of N II spectral lines [PDF]
Serbian Astronomical JournalThe Stark broadening parameters, widths, and shifts, for spectral lines within the 45 N II multiplets, were calculated for collisions with electrons, protons and helium ions, by using the semiclassical perturbation method. The obtained data were

On the influence of Stark broadening on Si I lines in stellar atmospheres
, 2003 We study the influence of Stark broadening and stratification effects on Si\i lines in the rapidly oscillating (roAp) star 10 Aql, where the Si\i 6142.48 \AA and 6155.13 \AA lines are asymmetrical and shifted.

Stark broadening of Xe II lines [PDF]
Astronomy and Astrophysics Supplement Series, 1996 We present here Stark widths and shifts for 20 Xe II multiplets which are of interest for laboratory plasma research as well as for the analysis of Hg – Mn stars spectra. For calculations the modified semiempirical approach was used. The obtained results are compared with the available experimental data.
