Stark broadening of spectral lines of multicharged ions of astrophysical interest. XX. O VII and MG XI spectral lines

Using a semiclassical perturbation approach, we have calculated electron-, proton-, and He III-impact line widths and shifts for 14 O VII and 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- 5000000 K. For lower perturber densities, the Stark broadening parameters are proportional to the perturber density.
