Abstract
Fluorescence cross sections for the production of the CO 2 + [A 2 Π u , B 2 Σ u + → X 2 Π g ] bands are presented at several vacuum ultraviolet (vuv) wavelengths between 462 and 715 Å. The cross sections, for incident vuvphotons from 600 to 680 Å, are 19 Mb for the production of CO 2 + (A 2 Π u ) and 7 Mb for CO 2 + (B 2 Σ u + ) and decrease monotonically toward the shorter wavelength region. The relative fluorescence cross sections of the observed sequences are also given for the various incident photon energies.
