MQDT and wave packet study of dissociative recombination of Ne$_{2}^{+}$

ORAL

Abstract

We report cross sections for the dissociative recombination of the Ne$_{2}^{+}$ molecular ion following collision with a low energy electron. This reaction plays a very important role in many gaseous discharges. The process is shown to be dominated at low energy by the lowest $^{1,3}\Sigma_{g}^{+}$ resonant dissociative states of Ne$_{2}$. The energy positions and autoionization widths of these doubly excited dissociative states are obtained from electron scattering calculations using the Complex Kohn Variational method while the dissociation dynamics is studied using both multichannel quantum defect theory(MQDT) and wave packet methods.
