A general method of calculating the time-dependent matrix elements needed for multistate impact-parameter calculations of atom-atom inelastic cross sections is presented and applied to the collision processes H(1s)+He(11S)-->H(2s, 2pm)+He(11S). Cross sections calculated in the distorted Born, two-state, and four-state impact-parameter approximations over the incident energy range 1.0 keV<=E<=200.0 keV are compared with previous experimental results and first Born-wave calculations. The first Born-wave calculations are in better agreement with the experimental measurements than are the distorted Born, two-state, and four-state impact-parameter calculations, but the fact that the corrections to the first Born become significant for v<=1.0 a.u. suggests that the good agreement may be accidental. Polarization fractions are calculated, and good agreement is shown with experiment for v<=0.8 a.u.
