Scientific paper

Information regarding Stark broadening data is required for stellar and laboratory plasma diagnostic, atomic abundances, and opacity calculations. Quantum-mechanical and semiclassical methods for the calculation of Stark broadening parameters are available. However, their utilization requires often a considerable computational effort. In addition, needed atomic data are not always available. For these reasons, approximate methods can be very useful. The present investigation is concerned with an approximate method reported by Dimitrijevic and Konjevic (1980, 1981). The utilized formula is suitable for singly as well as for multiply charged ion lines. Data of Stark width calculations conducted with the considered method for C III and N IV resonance lines are compared with other data.
