Scientific paper

Expressions are obtained in analytical form from the low temperature limit of modified semiempirical formulas which can be useful for simple estimates of Stark broadening parameters of single and multiple charged ion lines in plasmas. The estimate requires only a knowledge of atomic data for ionization potentials, energy levels and orbital quantum numbers of the upper and lower level of the considered transition. When the nearest perturbing level is not sufficiently far from E-sub-j, an alternate pair of formulas must be used.
