Stark broadening of spectral lines of multicharged ions of astrophysical interest

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 $10^{18}-10^{22}\;{\rm cm}^{-3}$ and 48 Ca X multiplets for perturber densities $10^{17}- 10^{22}\;{\rm cm}^{-3}$. In both cases the temperature range is $T = 200000 - 5000000\;{\rm K}$. For lower perturber densities, obtained results are linear with perturber density
