Using the semi-classical perturbation approach by Sahal-Bréchot (1969 Astron. Astrophys. 1, 91, 2 322; 1974 Astron. Astrophys. 35 321; 1991 Astron. Astrophys. 245 322) updated by Dimitrjević and Sahal-Bréchot (1984 J. Quant. Spectrosc. Radiat. Transf. 31 301; 1995 Physica Scripta 52 41) and by Ben Nessib et al. (1996 Physica Scripta 54 608) we have calculated Stark broadening widths of several C II, N II and O II spectral lines and input TOPbase (Opacity Project) sophisticated atomic structure data into the Sahal-Bréchot’s computer code. Then we have compared our results with those of available experiments and with Griem’s (1974) simplified semi-classical data. We show that our theoretical results, the simplified semi-classical calculations and experimental values are in good agreement. We also give new values of Stark broadening widths for several transitions of singly-ionized nitrogen and oxygen.
Abstract. Using a modified semiempirical approach, we have calculated Stark broadening full widths at half maximum for 25 OII multiplets for temperatures from 5000 K up to 80 000 K using the needed oscillator strengths from the sophisticated atomic structure data base TOPbase. Then we compared our results with experimental data for 41 OII spectral lines and with the available semi-classical calculations to test the applied method and the accuracy of the results obtained.
Using the semiclassical approach by Sahal-Bréchot [Astron. Astrophys. 1, 91 (1969), ibid. 2, 322 (1969)], we have calculated Stark shifts for CII, NII and OII spectral lines. The needed oscillator strengths have been obtained from the sophisticated atomic structure data base "TOPbase". Then we have compared our results with available experimental ones and with other theoretical results. We give also new values of Stark shifts.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
