It has already accounted in the bibliography that the CDW-EIS model fails to account some anti-screening effects which arise when dealing with dressed projectiles. In fact, the transition amplitude related with short-range electronic interactions is responsible of these phenomena. Also, it is the asymptotic nature of the eikonal approximation which makes it an unsuitable approach to calculate such particular transition amplitude when dressed projectiles are involved. In this work we propose to replace the initial channel eikonal phase with the hydrogenic continuum distortion factor.
