Abstract

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