摘要：

Cross section dependence on collision energy (0.1-5.0 keV) has been determined for exit channels Rb(5 P-2(1/2,3/2)) and Na(3 P-2(1/2,3/2), 4 D-2(5/2,3/2), 5 D-2(5/2,3/2), 7 (2)(S1/2), 6 D-2(5/2,3/2)) in the Rb + Na+ collision. Branching ratios between different J-components are also reported for the first two channels. Polarisation measurements have made it possible to obtain magnetic cross sections for the Na(3 P-2(3/2)) formation. Results for the first electron capture have been interpreted qualitatively in terms of a linear Landau-Zener-Stuckelberg model and ab initio calculations. (C) 1997 Elsevier Science B.V.
