Abstract

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.
