This paper presents the results of an experimental study of the Stark broadening and a shift of some double‐ionized argon spectral lines in a plasma of a low‐pressure‐pulsed arc. Electron densities of (3.5–9.0) × 1022 m−3 are determined by a two‐wavelength interferometry method and electron temperatures of 16 000–24 000 K are determined from the Boltzmann plot of 13 Ar ii spectral lines. The Stark parameter results obtained are analysed and compared with the available experimental results of other authors as well as with the calculated values obtained from modified semi‐empirical formulae. All investigated spectral lines belong to the ultraviolet spectral region. The data obtained can be of astrophysical interest.

This work reports new data for the Stark parameters of doubly ionized krypton spectral lines. Stark widths and shifts of Kr III lines belonging to the UV region (245-300 nm) have been measured. A low-pressure pulsed arc, containing a mixture of 8% krypton and 92% helium, was used as a plasma source. Measured electron densities and electron temperatures were in the range (0.7-2.0)×10 23 m −3 and 16 000-20 000 K, respectively. Experimentally obtained data were compared to theoretical results calculated using simplified modified semiempirical formulas.

Aims. The aim of this work is to provide Stark parameters of low intensity Xe II and Xe III spectral lines from which scarce or null previous information exist.This work completes the measurements of ionized Xenon parameters developed in the last few years and extends Stark parameters database for astrophysical applications. Methods. All Stark parameters were measured in a pulsed arc plasma with 95% of helium and 5% of xenon. Measured electron densities and temperatures were in the range of (0.2−1.7) × 10 23 m −3 and 18 000−25 500 K, respectively. Results. As a whole 25 Stark widths and 29 shifts of Xe II spectral lines have been measured, along with 10 Stark widths and 6 shifts of Xe III. Some of the presented data are compared to theoretical values calculated using modified semiempirical formulae, as well as to other available experimental results.
