摘要：

Electron-impact excitation and ionization of H-like ions of nuclear charge Z = 2, ... , 8 have been calculated from thresholds to high energies, with a particular focus on spin asymmetry of the cross sections. It is found that the importance of electron exchange is undiminished with increasing Z. Away from resonance regions, scaling considerations allow for accurate nonrelativistic estimates of the total-electron-spin-dependent cross sections for Z > 8.
