Abstract
State-selective, non-dissociative electron capture processes by very s low nitrogen dications from atoms (He, Ne and Ar) and molecules (D-2, N-2 and O-2) has been studied experimentally at impact energies of 28 eV by means of ion translational energy spectrometry and theoretically by means of ab initio configuration interaction calculations of the p otential energy curves involved in the electron capture process. Infor mation is obtained on the principal quantal states involved in the inc oming and outgoing channels; indications are obtained that the electro n capture occurs primarily into electronically-excited states of N-2() and that the dynamics may involve non-Franck-Condon routes.
