Formation of He₂⁰and He₂²⁺molecules by charge exchange collisions of He₂⁺ions in the sub-MeV region

Abstract

The six dissociation and two charge exchange channels populated by single collisions of He2+ molecular ions have been studied at 400 and 800 keV. The use of the grid method enabled the separation of undissociated and dissociated channels having equal energies and charges. Both He20 and He22+ molecules have been observed.
