Abstract
Using a semiclassical perturbation approach, we have calculated electr on-, proton-, and He III-impact line widths and shifts for 4 Si XI mul tiplets for perturber densities 10(18) - 10(23) cm(-3) and temperature s T = 500000 - 4000000 K, and for 61 Si XIII multiplets for perturber densities 10(16) - 10(23) cm(-3) and temperatures T = 500000 - 6000000 It. For lower perturber densities, obtained results are linear with p erturber density.
