Absolute and relative cross sections Q were obtained for the charge-transfer reaction HCl/sup +/+Xe..-->..HCl+Xe/sup +/. The reactants and products are in their ground electronic states, but HCl/sup +/ and HCl may be vibrationally and rotationally excited. The studies were made by a merging-beams technique for a relative kinetic energy W of the reactants from nominally 0.01 to 870 eV. Relative Q and laboratory-energy distributions of Xe/sup +/ indicate that (a) near-resonant charge transfer preceded by a capture, or orbiting, collision occurs for 0.01< or =W< or approx. =0.6 eV, (b) near-resonant charge transfer without capture occurs for 0.6< or approx. =W< or approx. =200 eV, and (c) nonresonant charge transfer is dominant for W> or approx. =400 eV. The near-resonant charge transfer is apparently fostered by the matching of electronic-vibrational-rotational energy levels of the entrance and exit channels. This results in the conversion of internal energy of HCl/sup +/ into internal energy of HCl.
