Symmetry-resolved x-ray absorption fine structure and resonant Auger-spectator-electron decay study of O 1s→Rydberg resonances in O2

• A series of resonant Auger-electron spectra excited at selected photon energies across the O 1s -> Rydberg resonances in O-2 has been measured. Applying a spectator-electron shake relaxation model originally introduced for atomic resonant Auger-electron spectra, and using, to a large extent, the assignments for the core-excited resonances available from the literature, many of the observed spectator Auger-electron final states are assigned in terms of cationic Rydberg series. Vice versa the resonant Auger-electron spectra are used for consistency tests of the literature assignments for the core-excited intermediate Rydberg states. For some of the latter, alternative assignments are proposed for reasons discussed.
