Calculated Stark widths of the triply charged argon ion Ar IV

Monthly Notices of the Royal Astronomical Society, Volume 526, Issue 3, pp.3861-3870

In this work we studied the Stark widths of Ar IV ion which are important for modelling atmosphere of some particular stars. Using semiclassical perturbation and modified semi-empirical approach, we present in this work Stark widths of triply ionized argon Ar IV spectral lines which will be implemented in the STARK-B data base. Energy levels and oscillator strengths needed as input for Stark width calculations were obtained from the atomic structure data base TOPbase. If we need to interpolate these Stark widths at different temperatures for the studied transitions of Ar IV, we use a simple and accurate fitting formula based on a least-squares method. The calculated values were compared to the existing experimental and calculated Stark width values.
