Abstract:

Using a semiclassical perturbation approach, we have calculated electron-, proton-, and He III-impact line widths and shifts for 57 Na X multiplets for perturber densities 10¹⁷- 10²⁴ cm^-3 and temperatures T = 200 000 - 5 000 000 K. For lower perturber densities, the Stark broadening parameters are proportional to the perturber density.

Key words: lines: profile-atomic data
