The electron dynamics in p-He and He{sup 2+}-He collisions have been investigated on the level of the independent electron model by using the two-center basis generator method. Projectile angular-differential cross sections for various one- and two-electron processes involving electron transfer have been calculated with the eikonal approximation. Overall, the calculated cross sections are in good agreement with the most recent experimental cold target recoil ion momentum spectroscopy data taken at impact energies in the range from 40 to 630 keV/amu. This demonstrates, somewhat surprisingly, that electron correlations play but a minor role for the processes and the energies considered.
