Dissociative Electron Attachment to ClCN and BrCN

ClCN and BrCN are pseudobihalogens. They have the interesting property that since both fragments, CN and Cl/Br, have positive electron affinities, two fragment channels are open. This means that dissociative electron attachment is possible into both CN$^{-}$ and Cl$^{-}$/Br$^{-}$ channels. The resonance parameters for these systems are obtained from electron scattering calculations using the Complex Kohn variational method. These resonance parameters are used as input into a full three dimensional wave packet calculation using the multi-configuration time-dependent Hartree (MCTDH) method. The resonances leading to dissociation into the product channels will be discussed and the calculated cross sections will be reported and compared to available experiment.
