The laboratory measurement of processes in- volved in terrestrial airglows is essential in developing di- agnostic tools of the dynamics and photochemistry of the upper atmosphere. Dissociative electron recombination of O + in the ionospheric F-region is expected to produce both O( 1 D) and O( 1 S) which are the sources of the 630.0 nm red airglow and the 557.7 nm green airglow lines, respectively. We present both theoretical and experimental evidence, the latter from a heavy ion storage ring technique, that the O( 1 S) quantum yield from O + (v = 0) is a strong function of the electron temperature due to a molecular resonance phenomenon. At present the O + (v = 0) theoretical and laboratory recombination data cannot explain rocket obser- vations of the ionospheric green and red airglows (Takahashi et al. 1990; Sobral et al. 1992). |
