Abstract
Using a semiclassical perturbation method, we have calculated electron-, pro ton-, and ionized helium-impact line widths and shifts for 52 Be III multiplets as a function of temperature and perturber density. Electron temperatures are 10 000 K; 20 000 K; 50 000 K; 100 000 K; 200 000 K and 300 000 K and perturber densities are from 10 11 cm -3 up to 10 21 cm -3. The obtained results have been used for discussion of regularities and systematic trends along spectral series.
