Aims. We consider the effect of Stark broadening on the shapes of Cr ii spectral lines observed in stellar atmospheres of the middle part of the main sequence. Methods. Stark broadening parameters were calculated by the semiclassical perturbation approach. For stellar spectra synthesis, the improved version synth3 of the code synth for synthetic spectrum calculations was used. Results. Stark broadening parameters for Cr ii spectral lines of seven multiplets belonging to 4s − 4p transitions were calculated. New calculated Stark parameters were applied to the analysis of Cr ii line profiles observed in the spectrum of Cr-rich star HD 133792.Conclusions. We found that Stark broadening mechanism is very important and should be taken into account, especially in the study of Cr abundance stratification.

Stark full widths at half maximum of six 4s -4p Sc IV spectral lines, broadened by collisions with electrons, have been calculated for electron density of 10 17 cm −3 by using the modified semiempirical method. The results are provided for temperatures from 10 000 K to 160 000 K. They are used also to discuss the similarities of Sc IV spectral lines within multiplet, supermultiplet and transition array. Obtained results will be included in the STARK-B database which is also a part of Virtual atomic and molecular data center(VAMDC).

“…Energy levels necessary for present calculations have been taken from Salo man (2010). The needed oscillator strengths have been calculated within the Coulo mb approximation by using the method of Bates & Damgaard (1949) and the tables of Oertel & Shomo (1968). For higher levels, when there is no the corresponding data in Oertel & Shomo (1968), the required oscillator strengths have been calculated according to the article of Van Regemorter et al (1979).…”

Stark broadening parameters, full wi dth at half maxi mum of s pectral line and shift, have been calculated for 3 spectral lines of Ar VII, for broadening by electron, proton, and He III i mpacts. For calculations, the semiclassical perturbation approach in the impact approxi mation has been used. The results are provi ded for temperatures from 20 000 K to 500 000 K and for an electron density of 10 17 cm -3 . Obtained results will be included in the STARK-B database which is also included in Virtual atomic and molecular data center (VAMDC).
