• The absolute photoionization cross sections of the Be-like F5+ ion have been calculated using a non-iterative variational R-matrix method combined with multichannel quantum-defect theory. Total and channel photoionization cross sections for the ground 2s^{2} 1 state and the excited 2s2p 3,1 states of the Be-like F5+ ion in the photon energy region from the first threshold up to the F6+ 3d threshold have been also calculated and presented. The low lying autoionizing resonance structures arising from the ground and excited states are identified, characterized and discussed. Our calculational results, which show excellent agreement between length and velocity gauges, are compared with the available previous calculations, and overall good agreement is found.
