Abstract

Astronomy & Astrophysics Physical Sciences Science & Technology Spectroscopy Technology
Using a semiclassical perturbation approach, we have compared Stark broadening parameters for 16 Si V multiplets calculated with oscillator strengths obtained with the SUPERSTRUCTURE code and within the Coulomb approximation. In order to complete Stark broadening data for most important charged perturbers in stellar atmospheres, Stark broadening parameters for proton-, He II-, and Si II-impact line widths and shifts axe presented also.
