摘要：

We present a theoretical study of state selectivity for electronic processes occurring in the course of collisions between ions and atoms. This analysis is performed within the semiclassical atomic basis impact parameter treatment in combination with the eikonal method to obtain angular differential cross sections and alignment and orientation parameters. We apply the formalism to H+-Na collisions in the 0.75-5.0 keV energy range for which new experimental data are available, cf the companion paper and the comparison there with our theoretical predictions. We report and discuss the orientation of the final H(2p) and H(3p) capture states for an initial Na(3s) state and for initially oriented Na(3p+/-1) states.
