Description
The lattice time-dependent Schroedinger equation (LTDSE) and atomic orbital close coupling (AOCC) methods are applied to calculate the charge transfer cross sections for H+ + He+ and He2+ + Li2+ collisions in the velocity range of 0.5-4.0 atomic units. The comparison of the results is made with those of other theoretical methods and with measurements. This analysis is used to provide a test of the accuracy of LTDSE and AOCC, and to help establish a consensus of theoretical results in comparison with the measurements for these ion-ion collisions
