Dissociative recombination of Cl2

Theoretical studies of low energy electron collisions with Cl2+ leading to direct dissociative recombination are presented. The relevant potential energy curves and autoionization widths are calculated by combining electron scattering calculations using the complex Kohn variational method with multireference configuration interaction structure calculations. The cross sections and the thermal rate coefficients for DR of Cl2+ are calculated and the relative influences from vibrational excited target ions are investigated.
