The two-electron process of simultaneous electron transfer and excitation (TE) in atomic collisions is studied within the close-coupling method for the example system He⁺+H. The calculated energy dependence of the population of various helium doubly excited states is analyzed for the role of electron correlations in the resonant and nonresonant contributions to the TE process which are included coherently. It is predicted that the impact-parameter-dependent state-selective TE probabilities show conspicuous peak structures.
