  Nonrelativistic collision of proton and antiproton with hydrogen atom
described by solving time-dependent Schrodinger equation numerically. Coulomb
wave function discrete variable method (CWDVR) had been used to calculate
electron wave function evolution, while projectile defined classically, moving
along the straight line trajectories with constant velocity. The ionization
amplitude calculated by projection of the wave function into continuum wave
function of the hydrogen electron. The differential cross sections calculated
depending on projectile impact energy, scattering angle and electron ejection
energy and angles. Our results in good agreement with the relativistic
calculation results.
