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 CO2. 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 2Πu shape resonance in CO2 proceeds to dissociate to CO(1Σ+) + O-(2P) by DEA.

The 4.4 eV data (b) was measured using the Auburn apparatus on a colder CO2 target that is better spatially confined, resultingmore » in a higher momentum resolution. In each plot the incident electron direction is longitudinal, pointing upwards. The color-scales are linear and represent ion yield in arbitrary units.« less
