Abstract: New electron-impact line widths for eight Cr II multiplets have been calculated within the modified semiempirical (MSE) approach. Needed energy levels and radial integrals are calculated by different methods. The Stark widths are obtained as a function of temperature, for perturber density of 1017 cm-3 and have been compared with the approximate formula of Cowley and with recent experimental results. The obtained results are of interest for diagnostic and modeling of laboratory and stellar plasmas. The obtained data will be included in the STARK-B database, which is part of the Virtual Atomic and Molecular Data Center – VAMDC.
