Abstract

Energy levels and radiative rates for transitions among the lowest 97 fine-structure levels belonging to the (1s²2s²2p⁶) 3s²3p², 3s3p³, 3s²3p3d, 3p⁴, 3s3p²3d and 3s²3d² configurations of Fe XIII have been calculated using the fully relativistic GRASP code. Additionally, collision strengths for transitions among these levels have been computed using the Dirac Atomic R-matrix Code (DARC) of Norrington & Grant ([CITE]). Radiative rates and oscillator strengths are tabulated for all allowed transitions among the 97 fine-structure levels, while collision strengths are reported for some transitions at a few energies above thresholds. Comparisons are made with the available results, and the accuracy of the data is assessed.
