Abstract

We present photoionization cross sections and asymmetry parameters for the 2pi level of nitric oxide which are obtained from the direct solution of the e+NO+ collisional equations at the static-exchange level. These cross sections differ significantly from those obtained previously using a moment theory approach [J. J. Delaney, I. H. Hillier, and V. R. Saunders, J. Phys. B 15, 1477 (1982)]. The calculated cross sections show a broad nonresonant feature at a photon energy of 29 eV which is not as pronounced as observed experimentally. The sigma shape resonance in our cross section occurs at 14 eV which is about 5 eV below the feature in the measured cross sections attributed to this shape resonance. The probable role of autoionization and vibrational averaging on these cross sections is also discussed.
