Using a semiclassical approach, we have calculated electron-, proton-,
and ionized helium-impact line widths and shifts for 33 Sr I multiple
ts for perturber densities 10(13) cm(-3) (for stellar plasma research)
and 10(15) - 10(18) cm(-3) (for laboratory plasma research) and tempe
ratures T = 2 500 - 50 000 K.
