Abstract

We present sets of new atomic data for astrophysical and fusion plasma diagnostics. We calculate electron-impact excitation collision strengths and effective collisions strengths for the Be- and Mg-like isoelectronic sequences up to Krq+. We use the R-Matrix Intermediate-Coupling Frame Transformation method. We also study the accuracy of calculations for highly-excited states and give extrapolation rules to estimate the effective collision strengths and their error at high n. We demonstrate the importance of a well converged CI/CC expansion in the R-matrix calculation to get good quality results, mainly for highly-excited states.
