Charge transfer excitation in N+ + CO2 collisions under beam conditions

For the N+ + CO2 collisions in the 6–1000 eVlab energy range a charge transfer excitation was observed. Luminescent charge exchange processes lead to the formation of the CO 2 + (A, B) states. The relative chemiluminescence cross-sections for these reactions are measured. The cross-section value for the reactions leading to the CO 2 + (A + B) states is constant in the 400–1000 eVlab collision energy range and is estimated to be equal to 4 × 10−17 cm2.
