Stark broadening of solar Mg I lines

Abstract

Using a semiclassical approach, we have calculated electron-, proton-, Mg II-, Si II-, Fe II-, and Ar II- impact line widths and shifts for 267 Mg I multiplets, in order to provide the needed Stark broadening parameters for all important perturbers for investigation of Solar and laboratory plasma. An analysis of Solar Rydberg lines in the far infrared spectrum has been performed as well.
