Abstract

In this paper, certain aspects of ion-atom collisions at intermediate energies (E ≈ 50 – 1000 keV/u) which involve so called two-center effects will be discussed. In particular, work on the fundamental system H+ + He will be emphasized, because of the availability of experimental data and the tractability of theoretical calculations using a variety of methods. Furthermore, this review will concentrate on features of the doubly differential cross section for ionization in such ion-atom collisions because they dramatically reflect the importance of the interactions of the ejected electrons with both the projectile and target ionic centers. Comparisons are made with the results of single-center treatments such as the first-order Born approximation in order to underscore the significance of two-center effects. Works considering antiproton-impact and the interchange of electrons between ionic centers in multiply-charged ion — manyelectron atom collisions will also be discussed. Finally, the failure of the Born picture in predicting the role of projectile nuclear charge screening in collisions involving partially stripped ions is described in terms of its relationship to observed anomalies in the binary peak magnitude.
