Abstract
We present detailed comparisons between the two quantal approaches—hyperspherical close-coupling and common-reaction-coordinate close-coupling methods—on an exemplary case of collisions at center-of-mass energy from up to . It is shown that the partial-wave charge-transfer cross sections from the two approaches agree very well at low energy below down to . This good agreement is a strong indication of the validity of both methods. The small difference at very low energies and the convergence with respect to the number of channels in both approaches at higher energies are also discussed.
