Electron excitation collision strengths for fine-structure transitions 3s23p5-3s3p6, 3s23p5-3s23p43d and 3s3p6-3s23p43d in Fe x, are calculated using a 180-level Breit-Pauli R-matrix calculation containing the above levels together with those from 3s3p53d and 3s23p33d2 configurations. The collision strength is averaged over a Maxwellian velocity distribution to obtain the effective fine-structure collision strengths as a function of electron temperature from . We show that low-energy resonances enhance the effective collision strength, with significant effects on level populations.
