Abstract
The potential energy curves and the coupling matrix elements of the 1S IGMA+ and 1PI states involved in the collision of the B3+ (1s2) multic harged ion on a He target have been calculated by means of an ab initi o method with configuration interaction. The total and partial capture cross-sections have been determined, using a semiclassical method. Th e results are in good agreement with experiment, exhibiting a strong i nfluence of rotational coupling even at low energies.
