Using a semiclassical approach, we have calculated electron-, proton-, and He III-impact line widths and shifts for 4 Ca IX multiplets for perturber densities tex2html_wrap_inline693 and 48 Ca X multiplets for perturber densities tex2html_wrap_inline695. In both cases the temperature range is tex2html_wrap_inline697. For lower perturber densities, obtained results are linear with perturber density.
