Stark broadening parameter tables for spectral lines of multicharged ions of astrophysical interest. II. Si IV lines.
Résumé
Using a semiclassical approach, the authors have calculated electron-, proton-, and ionized helium-impact line widths and shifts for 39 Si IV multiplets as a function of temperature for perturber densities 1015cm-3 and 1018- 1821cm-3.
