摘要：

A theoretical study of the ionization process in H + p¯ collisions was carried out by solving the time-dependent Schrodinger equation with the split-operator method and the generalized pseudospectral method in the energy representation. Emphasis was on the numerical accuracy and the numerical convergence. The calculated results are confirmed to be accurate and stable, and consistent with various checks within a 3% discrepancy.
