Scientific paper

By using the semiclassical perturbation method, Stark widths and shifts have been calculated for the TeI 6s 5S° - 7p 5P (5125.2 Å) multiplet, of interest for CP star plasma studies. Results were applied to the investigation of the influence of Stark broadening on CP star spectra. It was found that layers exist in the stellar atmospheres considered where the Stark broadening contribution is comparable to or larger than the Doppler width.
