Abstract
Using a semiclassical perturbation approach, we have calculated electr on-, proton-, and He III-impact line widths and shifts for 14 O VII an d 18 Mg XI multiplets. For O VII, perturber densities are 10(17)-10(23 ) cm(-3) and temperatures T = 100000 - 2000000 K. For Mg XI, perturber densities are 10(18)-10(24) cm(-3) and temperatures T = 500000 - 5000 000 K. For lower perturber densities, the Stark broadening parameters are proportional to the perturber density.
