“…The experimental data were obtained form various plasma sources with different plasma conditions and with different plasma diagnostic methods. These experimental conditions are summarized in Konjević & Roberts (1976); Konjević et al (1984); Konjević & Wiese (1990); Konjević et al (2002); Lesage (2009 Kusch (1971), which show higher values for He I 3889 (see Fig. 23) and lower values for He I 5016 (results not shown in Fig.…”

Context. The Stark broadening of the spectral lines of the wavelengths 501. 6, 667.8, 728.1, 388.9, 587.6, and 706.5 nm from neutral helium in plasmas are studied theoretically and experimentally. Aims. The aim of this work is to provide information about the connection between the shape and width of spectral lines and the electron density and temperature to be used as a diagnostic tool. Methods. The theoretical calculations were carried out through molecular dynamics computer simulations with noninteracting particles. The experimental measurements were done in a plasma of pure helium generated in an electromagnetically driven T-tube. The plasma diagnostics used previous results about the Stark broadening of the He I 447.1 nm and He I 492.2 nm lines and the coherence between the shape of these spectra and those obtained here. The electron temperature was obtained through a Boltzmann-plot of eight lines of Si II. Results. Several tables of width and shift are provided in a wide range of electron density and temperature. Furthermore, we supply several fitting formulas, which allow calculating the plasma electron density from the measured values of the spectral line widths. The results obtained in the laboratory and in the simulations are compared with the data from the literature.

“…Progress in studying different kinds of Stark broadening regularities of astrophysical interest was enabled by a monograph by Griem (1974) and a series of critical review papers devoted to the theoretical and experimental investigation of Stark broadening of numerous spectral lines from different atoms and ions (Konjevic, Dimitrijevic & Wiese 1984a, 1984bKonjevic & Wiese 1976a, 1976bKonjevic et al 2002;Lesage 2009). This, together with the Stark B database prepared by Dimitrijevic & Sahal-Bréchot (1992, 1994, opens an opportunity for studying different kinds of Stark broadening parameter regularities more seriously within similar spectra (Puric & Š cepanovic 1999;Šcepanovic & Puric 2003;Puric et al 2008;Tapalaga, Dojčinovic & Puric 2011;Elabidi & Sahal-Brechot 2011).…”

Abstract:The dependences of Stark width on the upper-level ionization potential within different series of the neutral beryllium spectral lines have been studied. The dependences previously observed for electron impact contribution to the Stark widths were also obtained for the proton impact contribution. The emphasis is on the fine structure influence on the studied Stark parameter dependences. The influence of temperature on the dependences of Stark width parameters has been demonstrated. The relations found can be used in both cases for prediction of new Stark broadening data, thus avoiding much more complicated procedures.

“…They used photographic techniques and Konjević & Wiese (1990) in his critical analysis of the experimental Stark broadening data stated that "self-absorption may have been an important factor for the 4226.56 Å line" in his experiment. In Konjević et al (1984), the error bars of their results are critically estimated to be within ±50% (accuracy denoted as C in their notation). Musiol et al (1988) determined experimentally Stark widths of 9 lines from Ge I 4p 2 -4p5s and 4p 2 -4p4d transition arrays by using a wall-stabilized arc operated at atmospheric pressure with various mixtures of GeH 4 and Ar.…”
