    "abstract": "We develop an Over Barrier Model for computing charge exchange between ions\nand one-active-electron atoms at low impact energies. The main feature of the\nmodel is the treatment of the barrier crossing process by the electron within a\nsimplified quantum mechanical formulation which takes into account: (a) the\nprobability of electron reflection even for over-barrier scattering, and (b)\nthe discreteness of the receiving atom\u0027s quantum levels which strongly suppress\ncaptures far from the resonance condition. It is shown that inclusion of these\neffects yields a fairly good prediction of experimental data. We discuss also\nthe probability of electron re-capture by the target.",
