Ion–Atom Charge Transfer Reactions at Low Energies

Abstract

In this chapter, we review the over-the-barrier, Langevin-orbiting, Landau–Zener–Rosen, and molecular orbital close-coupling (MOCC), models used in calculations for low-energy ion–atom charge transfer reactions in which both the incident and exit configurations include at least one positively charged ion. We summarize theoretical descriptions for both radiative and nonradiative charge transfer processes.
