Stark broadening of Sr i spectral lines

Abstract

Using a semiclassical approach, we have calculated electron-, proton-, and ionized helium-impact line widths and shifts for 33 Sr I multiplets for perturber densities 1013 cm-3 (for stellar plasma research) and 1015 - 1018 cm-3 (for laboratory plasma research) and temperatures T = 2 500 - 50 000 K.
