Rearrangement in antiproton (p̄) and positronium (Ps) collisions, p̄ + Ps → H + e-, is a promising process to produce large amount of antihydrogen atom (H). The formation cross section is calculated by using a time-dependent coupled channel (TDCC) method. Numerical accuracy of the TDCC method is demonstrated in a calculation of Ps-formation cross sections in positron and hydrogen collisions. The present result shows a dominant peak of the cross section around a center of mass collision energy of 10 eV.
