J/A+AS/129/155 Si XI & Si XIII lines Stark broadening (Dimitrijevic+ 1998) ================================================================================ Stark broadening of spectral lines of multicharged ions of astrophysical interest XVIII: Si XI and Si XIII spectral lines Dimitrijevic M.S., Sahal-Brechot S. =1998A&AS..129..155D (SIMBAD/NED BibCode) ================================================================================ ADC_Keywords: Atomic physics Keywords: atomic data - line: profiles - plamas Abstract: Using a semiclassical perturbation approach, we have calculated electron-, proton-, and He III-impact line widths and shifts for 4 Si XI multiplets for perturber densities 10^18^-10^23^cm^-3^ and temperatures T=500000-4000000K, and for 61 Si XIII multiplets for perturber densities 10^16^-10^23^cm^-3^ and temperatures T=500000-6000000K. For lower perturber densities, obtained results are linear with perturber density.
