On the applications of the modified semiempirical method for Stark broadening: the example of the alkali-like ion Sr II

Abstract

In this work, the different methods of Stark width calculations are presented briefly: We started with the fully relativistic method (Elabidi et al. 2004), after that the semiclassical perturbation (SCP) method (Sahal-Bréchot et al. 2014), the semiempirical (SE) method (Griem 1968), the modified semiempirical (MSE) method (Dimitrijević and Konjević 1980), the simplified modified semiempirical (SMSE) method (Dimitrijević and Konjević 1987) and the simplified formula (SF) methods as the Cowley formula (Cowley 1971). After that, by using the modified semiempirical (MSE) method, we calculated Stark widths for 12 Sr II multiplets for temperatures from 5000 to 50,000 K and electron density of 1017 cm −3 and compared them to other theoretical and experimental results.
