Cross sections for excitation to low-lying states and ionization of He{sup +} by antiproton impact are calculated in the energy range 1{endash}500 keV by solving the time-dependent Schr{umlt o}dinger equation on a numerical lattice. The results are compared with those of other theoretical approaches. Such comparisons allow a strenuous test of the lattice Schr{umlt o}dinger-equation approach for this fundamental collision system. {copyright} {ital 1997} {ital The American Physical Society}
