Description
The potential energy curves and the coupling matrix elements of the 1Σ+ and 1Π states involved in the collision of the B3+ (1s2) multicharged ion on a He target have been calculated by means of an ab initio method with configuration interaction. The total and partial capture cross-sections have been determined, using a semiclassical method. The results are in good agreement with experiment, exhibiting a strong influence of rotational coupling even at low energies. (orig.)
