An 11‐state R ‐matrix calculation is performed to obtain cross‐sections for the photoionization of the 1s 2 2s 2 S ground states of N v and O vi . For both ions at low photon energies, corresponding solely to the 2s photoionization cross‐section, excellent agreement is found with previous calculations. For higher photon energies, permitting inner‐shell photoionization of the 1s electron, excellent accord is found with the recent calculation of Nahar for O vi , whilst for N v resonance structure is found which previous calculations omitted.
