We have calculated the cross sections for various processes in He+ + H collision and compared them with experimental and theoretical data. The excitation cross sections to H(n = 2) states agree well with the measurements of Geddes et al. The Balmer-alpha emission cross section of H is approximately half the size of the experimental data of Donnelly et al. The electron capture cross section is close to the experimental data of Lockwood et al and Olson et al. The ionization cross section is in accordance with the experimental data of Hsu et al.
We have calculated the cross sections for the elastic, excitation, electron capture, and ionization processes in He+ + H collision using a semiclassical atomic orbital close-coupling method within two-electron treatment. The calculated data are compared with those of the experiments and previous theoretical calculations. The excitation cross sections to H(n = 2) states are in good agreements with the measurements of Geddes et al. The Balmer-alpha emission cross section of H is about half the size of the experimental data of Donnelly et al. The electron capture cross section is close to the experimental data of Lockwood et al and Olson et al. The ionization cross section is in accord with the experimental data of Hsu et al.
