Abstract

Formation of beams of negative ions by the process of dissociative electron attachment to a molecule AB (e- + AB → A + B-) is investigated. It is demonstrated that the initial rovibrational excitation of the molecule AB plays a significant role in enhancing the rate of production of negative ions. A simple physical picture, involving the formation of a transient resonant state of the molecular anion, is used to explain this enhancement.
