A three-dimensional lattice solution of the time-dependent Schr{umlt o}dinger equation for low quantum states (n{le}3) is combined with classical trajectory Monte Carlo results for high quantum states (n{ge}4) to predict total electron loss and total charge-transfer cross sections for proton collisions with atomic hydrogen at intermediate energies. The total charge-transfer cross sections range from 5{percent} above to 10{percent} below the furnace target measurements of McClure [Phys. Rev. {bold 148}, 47 (1966)], while the total electron-loss cross sections range from 5{percent} to 15{percent} above the pulsed crossed-beams measurements of Shah, Elliot, and Gilbody [J. Phys. B {bold 20}, 3501 (1987)]. The calculation of ionization as a difference between electron loss and charge transfer leads to theoretical ionization cross sections that are 10{percent} to 35{percent} larger than the crossed-beams measurements of Shah and Gilbody [J. Phys. B {bold 14}, 2361 (1981)] and Shah, Elliott, and Gilbody [J. Phys. B {bold 20}, 2481 (1987)]. {copyright} {ital 1999} {ital The American Physical Society}
