Stark broadening of spectral lines of multicharged ions of astrophysical interest

By using the semiclassical-perturbation formalism, we have calculated e lec tron-, proton-, and He III-impact line widths and shifts for 4 Sc X, 10 Sc XI, 4 Ti XI and 27 Ti XII multiplets, significant for analysis, investigation and modeling of different plasmas in solar and stellar physics, physics and technology. The results are presented as a function of temperature and perturber density
