摘要：

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.
