Photoionization cross-sections out of the fine-structure levels (2s²2p^{4 3}P_2,0,1) of the O-like Fe ion Fexix have been reinvestigated. Data for photoionization out of each of these fine-structure levels have been obtained, where the calculations have been performed with and without the inclusion of radiation damping on the resonance structure in order to assess the importance of this process. Recombination rate coefficients are determined using the Milne relation, for the case of an electron recombining with N-like Fe ions (Fexx) in the ground state to form O-like Fe (Fexix) existing in each of the fine-structure ground-state levels. Recombination rates are presented over a temperature range ∼4.0<= log T_e<=7.0, of importance to the modelling of X-ray emission plasmas.
