Abstract
We report results of an experimental study of Stark broadening and shift of analogous transitions of S i i, Cl i i i, Ar i v, Cl i i, and Ar i i i in plasma of a low-pressure pulsed arc. These results, together with other available experimental data, were used for investigation of Stark broadening and shift of analogous transition of isoelectronic ions. Results of modified semiempirical calculations are used for comparison.
