摘要：
Cross sections for the ionization-excitation of helium by fast charged-particle impact are calculated using the impact-parameter method and second-order perturbation theory. The inclusion of the two-step I mechanism in the calculations considerably improves our previous results. The dependence of the cross sections on the sign of the projectile charge is also investigated.
