Abstract
The neutral dissociation (ND) behavior of the Rydberg states converging to the c4Σu-state in O2+ was investigated using photon-induced fluorescence spectroscopy (PIFS). It was found that the dissociation of Rydberg states ndσg3Σu- with v=1 and nsσg3Σu-with v=0/1 leads, in the observed fluorescence wavelength region from 90 to 105 nm, mainly to an excited OI fragment either in the (4So)(n+1)/ns3So state or (4So)n/(n-1)d3Do state for the ndσg and nsσg molecular Rydberg states, respectively. The observed change of n corresponds to the conservation of the effective quantum number n∗.
