“…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.

“…The first group (Blagojević et al 1999(Blagojević et al , 2000 used a low-pressure pulsed arc and the second group (Wrubel et al 1996(Wrubel et al , 1998) used a gas-liner pinch. The accuracy of the experimental line widths is generally given by Konjević et al (2002) except for the few cases where other references have been mentioned. For 2s3s 1 S ← 2s3p 1 P transitions in F VI ions, we compared our results with w 1 of Elabidi et al (2008) as there are no experimental results available yet.…”

Aims. We present relativistic quantum mechanical calculations of electron-impact broadening of the singlet and triplet transition 2s3s ← 2s3p in four Be-like ions from N IV to Ne VII. Methods. In our theoretical calculations, the K-matrix and related symmetry information determined by the colliding systems are generated by the DARC codes. Results. A careful comparison between our calculations and experimental results shows good agreement. Our calculated widths of spectral lines also agree with earlier theoretical results. Our investigations provide new methods of calculating electron-impact broadening parameters for plasma diagnostics.

Stark broadening parameters are of interest for many problems in astrophysics and laboratory plasmas investigation. Ar II spectral lines are observed in many kinds of stellar atmospheres such as the atmospheres of B-Type stars and subdwarf B stars. In this work, we present theoretical Stark widths for Ar II spectral lines. We use the impact semiclassical perturbation approach. Our results are compared with the available experimental values. Finally, the importance of the Stark broadening mechanism is studied in atmospheric conditions of subdwarf B stars.
