Title: Dissociative electron attachment to carbon dioxide via the 2 Π u shape resonance

Abstract

Momentum imaging measurements from two experiments are presented and interpreted with the aid of ab initio theoretical calculations to describe the dissociative electron attachment (DEA) dynamics of CO 2. The dynamics of the transient negative ions of CO - 2 involve several conical intersections taking part in mechanisms that have only recently been understood. We address the problem of how the 4-eV 2Π u shape resonance in CO 2 proceeds to dissociate to CO( 1Σ +) + O -( 2P) by DEA.
