ORIENTATION OF THE (3P)P-2 STATE RESULTING FROM ELECTRON-CAPTURE IN AL3+ H COLLISIONS/

The orientation of the excited (2p(6)3p)P-2 state of Al2+, created by electron capture in collisions of Al3+ ions with atomic H and D, is in vestigated theoretically. The collision dynamics are described using a n adiabatic representation of the collision complex and calculations a re carried out in the 0.5 to 10 keV energy range. Total and differenti al cross sections for electron capture are presented. The range of sca ttering angles for which there is a strong propensity for orientation of the P-2 state is determined. The influence of the short range adiab atic potentials on the orientation at small scattering angles is discu ssed.
