摘要：

An implicit fast Fourier transform algorithm is implemented to solve the time-dependent Schrodinger equation with application to charge-exchange collisions. Cross sections are calculated for He2+ on H and compared with experiment and other theoretical results. A disagreement between previously published theoretical results is resolved.
