摘要：

Electron excitation to H n = 2 and n = 3 states in 1-300-keV/u He2+-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 n = 3 to 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 These structures are confirmed in as yet unpublished H2p-1s line-emission cross sections. No other information exists for energies below 10 keV/u.
