Dissociative electron attachment to N2O using velocity slice imaging

Abstract

The structure and dynamics of the negative ion resonances leading to dissociative electron attachment in N₂O are studied using the velocity slice imaging technique. Distinct momentum distributions are observed in the O⁻ channel for the dominant resonances below 4 eV which are considerably different than those reported so far. Also the relatively weak but distinct resonances at 8.1 eV and 13.2 eV are studied for their dynamics for the first time. For each of these resonances two different channels of dissociation are observed with differing angular distributions.
