Abstract:

Using a semiclassical perturbation approach, we have calculated electron-, proton-, and He III-impact line widths and shifts for 4 Si XI multiplets for perturber densities 1018- 1023 cm-3 and temperatures tex2html_wrap_inline503 K, and for 61 Si XIII multiplets for perturber densities 1016- 1023 cm-3 and temperatures tex2html_wrap_inline513 K. For lower perturber densities, obtained results are linear with perturber density.
