Hydrogen Ion-Molecule Isotopomer Collisions: Charge Transfer and Rearrangement

Abstract

A survey of existing data for collisions of isotopes of hydrogen atoms, ions, and molecules is presented. The survey was limited to atom – diatom ionic collisions and to energies generally less than about 10 keV/u. The processes include particle-rearrangement and charge transfer, including both dissociative and non-dissociative channels, with an emphasis on state-to-state (or state-selected) data, where available. Since the last survey (Linder, Janev and Botero 1995), a small number of investigations for deuterium and tritium ion-diatom systems have been performed, with some involving state-resolved data, which include the initial-state-resolved and state-to-state processes. While some progress has been made since the last survey, the database involving hydrogen isotope collisional processes, both total and state- resolved, is far from complete.
