The elastic scattering, Stark transitions and Coulomb deexcitation of excited antiprotonic hydrogen atom in collisions with hydrogenic atom have been studied in the framework of the fully quantum-mechanical close-coupling method for the first time. The total cross sections σnl → n'l'(E) and averaged on the initial angular momentum l cross sections σn→ n'(E) have been calculated for the initial states of (pp)n atoms with the principal quantum number n=3 - 14 and at the relative energies E=0.05 - 50 eV. The energy shifts of the ns states due to the strong interaction and relativistic effects are taken into account. Some of our results are compared with the semiclassical calculations.
