摘要：

Branching ratios and vibrationally resolved partial cross sections of O2+ have been measured for the X 2 Pi g, b 4 Sigma g− and B 2 Sigma g− ionic states for photon energies between 18.5 and 25.0 eV,. Vibrational branching ratios for the b 4 Sigma g− and B 2 Sigma g− electronic states show non-Franck-Condon behaviour arising from autoionising Rydberg states and the sigma u shape resonance at around 21.5 eV. A comparison between experiment and existing calculations is presented. © 1990 IOP Publishing Ltd.
