An atomic-orbital close-coupling method is applied to 
collisions for collision energies 1–200 keV. We show the cross sections for the elastic scattering, excitation to He(
S) and He(P), 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(S) and He(P) below 20 keV.
