Stark broadening and atomic data for Ar XVI

Abstract : Stark broadening and atomic data calculations have been developed for the recent years, especially atomic and line broadening data for highly ionized ions of argon. We present in this paper atomic data (such as energy levels, line strengths, oscillator strengths and radiative decay rates) for Ar XVI ion and quantum Stark broadening calculations for 10 Ar XVI lines. Radiative atomic data for this ion have been calculated using the University College London (UCL) codes (SUPERSTRUCTURE, DISTORTED WAVE, JAJOM) and have been compared with other results. Using our quantum mechanical method, our Stark broadening calculations for Ar XVI lines are performed at electron density Ne=1020 cm-3 and for electron temperature varying from 7.5 × 105 to 7.5 × 106 K. No Stark broadening results in the literature to compare with. So, our results come to fill this lack of data.
