Theoretical studies of cross sections and photoelectron angular distributions in the valence photoionization of molecular oxygen Academic Article uri icon


  • Photoionization from ground state of molecular oxygen leading to a number of ion states was investigated for photon energies using multichannel Schwinger method with configuration interaction. Substantial effects of the open-channel coupling were found in every channel in addition to numerous Rydberg-type autoionization states. The photoelectron angular distributions were computed and compared with the experimental data. Molecular orientation parameters under the fixed-nuclei approximation were calculated. Results were found in good agreement with experimental data.
