“…Our measured and calculated F III W values agree mutually (within 5%) and both lie above previously calculated (Dimitrijević & Konjević 1981) and measured (Purić et al 1988) values. Measured F III d values show evident scatter and within the experimental accuracy are practically equal to zero.…”

“…In the last five years fluorine spectral lines have become important for abundance investigations in various astrophysical plasmas (Lodders 2003;Zhu et al 2002;Highberger et al 2001). Only four experiments (Platiša et al 1977;Purić et al 1988;Djeniže et al 1991;Blagojević et al 1999; see also Lesage & Fuhr 1999;Konjević et al 2002, and references therein), deal with investigations of Stark broadening parameters (W, d) of singly ionized fluorine spectral lines. A number of calculations of the Stark parameters, related to the F II, F III spectral lines, on the basis of different theoretical approaches is presented in the literature (Griem 1974;Hey 1976;Hey & Breger 1981;Dimitrijević & Konjević 1981;Dimitrijević 1988a,b).…”

electron densities. For Stark parameters of two F II and five F III lines there are no other experimental data. The widths and shifts have also been calculated using the semiclassical perturbation formalism (SCPF) (taking into account the impurity of energy levels, i.e. that the atomic energy levels are expressed as a mix of different configurations due to the configuration interaction). Calculations have been performed for temperatures between 5000 K and 100 000 K for the F II spectral lines and between 10 000 K and 300 000 K for the F III spectral lines for electrons, protons and helium ions as perturbers. Our measured and theoretical Stark parameters are compared with existing experimental and theoretical data. Tolerable agreement was found among them.

“…The first experimental consideration of the Stark broadening of F III spectral lines was published in 1961 [5], and two unique reliable quantitative experimental determinations are given in [6][7]. Theoretical determinations of Stark broadening of F III spectral lines have been performed in [8][9][10] [6] with the calculations in [8], performed within the modified semiempirical approach [11].…”

∨ ic ′ a UDC 533.9.082.5Using a semiclassical approach, we have considered electron-, proton-, and ionized helium-impact line widths and shifts for the F III 2p 3 4 S o -3s 4 P resonant line. Moreover, for 10 F III multiplets where the full semiclassical perturbation approach is not applicable in an adequate way due to the lack of reliable atomic data, electron-impact line widths have been calculated within the modified semiempirical approach. Results are obtained as a function of temperature for perturber density of 10 17 cm -3 . The theoretical data obtained have been used to consider the influence of Stark broadening for A-type star atmosphere conditions.
