Energy levels and radiative rates for transitions among the lowest 97 fine-structure levels belonging to the (1s 2 2s 2 2p 6 ) 3s 2 3p 2 , 3s3p 3 , 3s 2 3p3d, 3p 4 , 3s3p 2 3d and 3s 2 3d 2 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 (2004) . Radiative rates and oscillator strengths are tabulated for
