Description
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 These structures are confirmed in as yet unpublished H2p-1s line-emission cross sections.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
