Fluorescence efficiencies of the A-X and B-X systems of CO⁺₂ in comets

抄録

Fluorescence models of the A-X and B-X band systems of CO⁺₂ have been constructed using molecular parameters available in literature. The models have been compared with the spectra of comets Austin (1989c1) and P/Giacobini-Zinner. From the best fit, the fluorescence efficiencies of the A-X and B-X band systems have been derived.
