Synopsis In the present work we extend the Continuum Distorted Wave - Eikonal Initial State (CDW-EIS) modelto the case of dressed projectiles. Double differential spectra are analyzed for single ionization of He atoms incollisions with U^{21+} ions as a function of the final energy and angle of the emitted electron. Structures interpretedin terms of coherent interference of short- and long-range contributions of the perturbative projectile potentialare observed.
