Excitation and charge-transfer cross sections for collisions of protons with lithium are calculated by direct solution of the time-dependent Schr{umlt o}dinger equation on a three-dimensional Cartesian lattice. For 5{endash}15-keV incident energies the 1s{sup 2} core of lithium may be treated effectively using a pseudopotential. For a proton incident on lithium, projections of the time-evolved wave function onto the lattice states of lithium yield excitation cross sections for the Li(2s){r_arrow}Li(2p,3l) transitions. For lithium incident on a proton, projections of the time-evolved wave function onto the lattice states of hydrogen yield charge-transfer cross sections for the Li(2s){r_arrow}H(2l,3l) transitions. The Li(2s){r_arrow}Li(2p) excitation and Li(2s){r_arrow}H(2s,2p) charge-transfer cross sections are found to be in good agreement with the crossed-beams experimental measurements of Aumayr {ital et al.} [J. Phys. B {bold 17}, 4185 (1984); {bold 17}, 4201 (1984); {bold 18}, 2493 (1985)]. {copyright} {ital 1999} {ital The American Physical Society}
