Identification of single charge transfer channels in –N₂ collisions by translational energy spectroscopy

Abstract

Single charge transfer reactions in the collision of

ions at a laboratory energy of 2 keV with N₂ were observed using translational energy spectroscopy (TES). Within the limitation of the energy analyser resolution (∼ 8/q eV, q being the ionic charge number), the translational energy spectrum shows a single broad charge transfer peak with a rich substructure. The latter looks like a conglomeration of closely spaced channels clumped together, corresponding mainly to charge transfer into excited states, rather than into the ground state. The reaction channel assignments were made using data available in the literature. Our findings are in accord with a recent experimental result, but there are no theoretical calculations to compare our experimental measurements with.
