Antihydrogen-formation cross sections in antiproton-positronium collisions were studied with a time-dependent coupled-channel (TDCC) method. To obtain accurate wave functions, nonuniform grid points were taken in the two-dimensional radial space. In a calculation of positronium-formation cross sections in positron-hydrogen collisions, high numerical accuracy of TDCC method was demonstrated.
