Description
Summary: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.
