Resumen:
The continuum distorted wave and the continuum distorted wave-eikonal initial state
approximations for electron emission in ion-atom collisions are generalized to the case of
dressed projectiles. The interaction between the dressed projectile and the active electron is
represented by the analytic Green?Sellin?Zachor (GSZ) potential. Doubly differential cross
sections as a function of the emitted electron energy and angle are computed. The region of
the binary encounter peak is analysed in detail. Interference structures appear in agreement
with the experimental data and are interpreted as arising from the coherent interference
between short- and long-range scattering amplitudes.
