Abstract:
Using a semiclassical perturbation approach, we have obtained Stark
broadening parameters for 16 Si V multiplets using atomic data
calculated ab initio with the SUPERSTRUCTURE code. In order to
complete Stark broadening data for the most important charged
perturbers in stellar atmospheres, Stark broadening parameters for
proton-, He II-, and Si II-impact line widths and shifts are also
presented. Results have been obtained for an electron density of
1017cm-3 as a function of temperature. Moreover, we have performed
the same calculations with oscillator strengths calculated within the
Coulomb approximation.

Global notes:
Note (G1): C/FWHM gives an estimate of the maximum perturber density for which
the line may be treated as isolated and tabulated data may be used
Note (G2): FWHM denotes Full Width at Half Maximum
Note (G3): A positive (resp. negative) shift is towards the red (resp. blue)
