Electron excitation to H {ital n}=2 and {ital n}=3 states in 1--300-keV/u He{sup 2+}-H collisions is studied within the semiclassical close-coupling method with atomic-orbital basis sets. Calculated excitation cross sections tie in smoothly with results from high-energy theories above 100 keV/u; they also agree with recently published H {ital n}=3 to {ital n}=2 line-emission cross sections (A. Donnelly, J. Geddes, and H. B. Gilbody, J. Phys. B 24, 165 (1991)). An interesting aspect of this study is that low-energy-excitation cross sections show structures that may be explained by the complex excitation mechanism. These structures are confirmed in as yet unpublished H2{ital p}-1{ital s} line-emission cross sections. No other information exists for energies below 10 keV/u.
