Abstract
Using the semiclassical perturbation approach, we have calculated electron- , proton-, He II-, Mg II-, Si II- and Fe II-impact line widths and shifts f or 189 Ca I multiplets as a function of temperature and perturber density. Perturbers selected here are the main perturbers in solar atmospheres. Obta ined results have been compared with the existing theoretical and experimen tal data.
