Wehave calculated the differential cross sections for the elastic, excitation toH(n=2), and electrontransfer
processes in He++Hcollision using a semiclassical atomic-orbital close-coupling method within two-electron treatment. The calculations have been implemented with four different basis sets to see the effects of electron-exchange, electron-transfer channels, and continuum channels. The results are compared with those of experiments and other calculations. -

An atomic-orbital close-coupling method is applied to H++He collisions for collision energies 1–
200 keV. We show the cross sections for the elastic scattering, excitation to He(21S) and He(21P), electron
capture to H(2 s) and H(2p), and so on. Depending on the processes, the present results agree with some experiments, but disagree with some. Discrepancies are also found between present results and those of
existent two-electron calculations for electron capture to H(2 s) and excitation to He(21S) and He(21P) below 20 keV. -

The collisions between proton and helium are treated with a semi-classical atomic orbital expansion for proton incident energies 5-150 keV considering two-electrons explicitly. Differential cross sections with respect to the projectile scattering angle are calculated for elastic scattering, 21S and 21P excitation, single electron capture, and single ionization. The agreement with experiments are mostly good, but non-negligible discrepancies are seen for the elastic scattering and the single electron capture with target excitation.
