Luminescent charge transfer of Co++(3 Pi,(1) Sigma(+)) ions in a beam with several atomic and molecular target species in a scattering cell was observed at 60-2000 eV(lab) projectile energies. Emission from Co+(B (2) Sigma(+) --> X (2) Sigma(+)) was spectrally analyzed with a resolution of up to 1 Angstrom full width at half maximum. In the case of CO++ +CO collisions, CO+(B) emission due to electron capture by the projectile and to target ionization were distinguished using isotopic substitution. CO+(A (2) Pi --> X (2) Sigma(+)) emission from the ionized target was also observed in this reaction. Similarly, with N-2 as a target, strong N-2(+) (B (2) Sigma(u)(+) --> X (2) Sigma(g)(+)) emission was observed. The absolute cross sections for CO+(B) formation are 1-5 Angstrom(2). The CO+(B) vibrational excitation at 200 eV can be explained by Franck-Condon transitions from the CO++((3) Pi)/((1) Sigma(+)) beam components in the ratio 1:2. At low energy the product CO+ vibrational excitation is higher, especially from collisions with Ar. The vibrational population distribution differs from that derived from earlier translational energy spectra, possibly due to a different CO++((3) Pi/(1) Sigma(+)) beam composition. The rotational excitation is in all strikingly low, even at low impact energy. This is ascribed to the large electron capture radius (similar to 2.8 Angstrom).
