Dissociation of highly charged N<SUB>2</SUB><SUP>q+</SUP> (q&gt;=2) ions via non-Coulombic potential energy curves

The kinetic energies released (KER) upon dissociation of N2q+ (q=2-10) ions are investigated by means of large scale, all-electron, ab initio, configuration interaction molecular orbital calculations. Results indicate that dissociation via non-Coulombic potential energy curves of N2q+ ions yields lower values of KER than would be expected from purely Coulombic considerations due to the significance of electronic charge density distributions in the internuclear region
