Abstract
We present in this paper new electron impact widths for 12 Ar V and 22 Ar VI lines. Neither experimental nor theoretical results have been found for these ions to perform comparisons. The results have been obtained using our quantum mechanical method. Results are presented for an electron density N-e = 10(18) cm(-3) and at a large range of electron temperatures (2 x 10(4)-10(6) K) required for plasma modelling. The atomic structure and collision data used for the calculations of line broadening are also calculated by our codes. We use our calculated widths to fit a dependence on electron temperature. We check that the obtained relation is valid for all the studied lines. The present results are required for many applications, especially for accurate spectroscopic diagnostics and modelling in astrophysics and in tokamaks, laboratory plasma physics, and technological plasmas.
