摘要：

The production of binary-encounter electrons in heavy-ion-atom collisions at high impact velocities is studied. The theoretical model used is the continuum-distorted-wave-eikonal-initial-state approximation. Deviations from classical predictions for the height and position of the associated peak in double-differential cross sections are determined. A simple adiabatic resonant-tunneling model is developed to interpret the physical meaning of the shift in the position of the binary-encounter peak.
