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.
