Scientific paper

The modified semiempirical method of Dimitrijevic and Konjevic (1980 and 1987) and of Dimitrijevic and Krsljanin (1986) has been applied to the Stark broadening of spectral lines from 127 astrophysically important multiplets of doubly and triply charged ions. Electron-impact line width results are presented for the prominent isolated lines of Be III through Ar III and B IV through Ar IV. A Coulomb approximation is used to evaluate the radial integrals.
