Abstract
A combined perturbation and close-coupling method is proposed to calculate cross sections for weak inelastic channels in ion-atom collisions. In this method, the time-dependent wavefunction is expanded in terms of basis functions of the dominant channels only, from which the perturbation method is applied to calculate cross sections for the weak channels. The method is applied to calculate probabilities for excitation and charge transfer to the n=2 states in p+H(1s) collisions in the intermediate energy region to check the validity of this approach. Cross sections for excitation to n=2, 3 and 4 levels are obtained and compared to experiment and other theoretical results.
