Competition between reaction channels in electron collisions of vibrationally excited

Abstract

The competing processes taking place in the reactive collisions of vibrationally hot with electrons, namely dissociative recombination, dissociative excitation, vibrational excitation, elastic scattering and vibrational de-excitation have been studied using a theoretical approach based on the multichannel quantum defect theory. The energy range considered is 0.1–12 eV. The high sensitivity of these processes to the initial vibrational state of is illustrated. In the case of a Franck–Condon distribution of initial vibrational levels, the comparison with the recent experimental results is performed.
