We calculate in this work quantum Stark broadening, radiative atomic data (energy levels, radiative decay rates, line strengths, oscillator strengths) and collisional parameters (collision strengths and effective collision strengths) for the two ions Ar X and Ar XIII. The convergence of collision strengths with partial waves of the incident electron has been also studied. We choose 18 Ar X and 18 Ar XIII lines to calculate their widths. Atomic data have been calculated using the University College London codes: SUPERSTRUCTURE, DISTORTED WAVE and JAJOM and have been compared with other results. Good agreement has been found between our radiative atomic and collisional results and other theoretical and experimental ones. Our Stark broadening data are the first to be published, so no comparisons have been performed for them.
