Wave packet studies of dissociative recombination

The study of dissociative recombination is complicated by the high energy and large number of channels that are open. Theory in this area has not kept up with experiment with few molecules studied. We will present our work on the study of the 'direct' dissociative recombination process, where one or more resonant states exist. The resonance parameters are taken from accurate electron scattering calculations and used as input to the dynamics calculations. We will illustrate the method with the study of DR in the HCN+ and HNC+ systems.
