We have calculated the partial and total photoionization cross sections for ground states 2s22p2 (3P) and excited states 2s22p2(1D,1S) ,2s2p3 (5So) of F3+ and Ne4+ ions and analyzed and identified the corresponding transitions of autoionization resonances for the ions in the photoionization processes. The obtained resonance structures of total photoionization cross sections are compared with the recent experimental ones and other theoretical calculations. It is shown that our results are in good agreement with the recent experimental ones.
