Scientific paper

Using a semiclassical perturbation approach, we obtained the Stark broadening parameters of 11 Cd I singlets and 13 triplets in ultra-violet and visible, and 24 Cd I triplets in infra red spectral ranges, for temperatures between 2500 K and 50000 K, and for perturber density of 1016 cm- 3. Also, we calculated within the same approach Stark broadening parameters for F III 2p3 4 So - 3s 4 P resonant line. Moreover, for 10 F III multiplets, Stark line widths have been calculated within the modified semiempirical approach, for temperatures between 10000 K and 300000 K, and for perturber density of 1017 cm-3. We compared our Stark broadeninig parameters for Cd I and F III with existing experimental data and other theoretical results, we also investigated the regularity within a spectral series of Cd I 5s2 1 S - np 1 Po and finally we analyzed the influence of Stark broadening mechanism of neutral cadmium and doubly ionized fluorine in comparison to the Doppler one for an A type star atmosphere.
