The N 1s photoionization of NO2 in the shape resonance region was investigated. It was confirmed that the shape resonance appeared only in the A1→B2 transition. The measured partial cross sections of the 1A1 and s3sA1 channels were found to exhibit maxima at the photon energies of 416.3 and 415.9 eV. The potential for the 1A1 N 1s-1s state was overestimated by the single-channel approximation. A possible role played by interchannel coupling between the two 1A1 and 3A1 target states and possibly with additional excited target states was also presented.
