Abstract
Differential cross sections for the double charge transfer process in C4+-He collisions are studied using a quantal two-channel molecular orbital close coupling expansion method. The calculated results for C4+ at incident energies of 1520 and 500 eV are found to be in good agreement with recent measurements. It is also shown that the quantal calculations and the experimental results are well reproduced by a semiclassical approximation. Comparison with the recent semi-empirical study of the same system by Barany et a1 is also discussed.Keywords
