Energy Transfer in Electron-Exchange Reactions at Low Kinetic Energies

Abstract

The energy transferred in single-electron-exchange processes in ${\mathrm{Ar}}^{++}$-He and ${\mathrm{Ar}}^{++}$-${\mathrm{D}}_2$ collisions has been experimentally determined for relative kinetic energies below 9 eV. The results confirm the "nearest-resonance" hypothesis for these two representative systems.
