Up: Stark broadening of neutral lines


1 Introduction

Neutral zinc spectral lines are present in stellar (see e.g. Sneden et al. 1991) and solar (see e.g. Biémont & Godefroid 1980; Grevesse 1984) spectra. Consequently, Stark broadening parameters of Zn I lines are of interest for a number of astrophysical problems, e.g. for abundance determinations, as well as for stellar plasma analysis, modeling and diagnostics. Such data are also of interest for laboratory plasma diagnostics, modeling and investigation (see Grechikhin 1969; Kusch & Oberschelp 1967; Salakhov 1975; Fishman et al. 1979; Dimitrijevic & Konjevic 1983; Lakicevic 1983; Rathore et al. 1985; Rao et al. 1989).

Within the semiclassical-perturbation formalism (Sahal-Bréchot 1969a,b; see also Sahal-Bréchot 1974; Dimitrijevic & Sahal-Bréchot 1984), we have calculated electron-, proton-, and ionized helium-impact line widths and shifts for 32 neutral zinc multiplets, as the continuation of our project to create a large Stark broadening data set for astrophysical and laboratory plasma research purposes.
