CLASSICAL TRAJECTORY STUDY OF ALIGNMENT EFFECTS IN THE CAPTURE PROCESS - HE2-LI-ASTERISK(2P-SIGMA,2P-PI) COLLISIONS()

A simulation method (CTMC) has been used to investigate the selectivit y and alignment effects on the capture process in He2+-Li(2p Sigma,2p Pi) collisions. The anomalous results of the experiment (similar to 5 0% error) as well as the AO calculation of Gieler et al. in case of ca pture into He II (n = 4) from the initial Li(2p Sigma) state are not found in the present work. Relative velocity and spatial overlap toget her mainly control the capture process in ion-atom collisions. The n-d istribution of the final capture state is also presented.
