【 摘 要 】

The post-version of the Continuum Distorted Wave (CDW) model neglects a part of the active electron- residual target interaction which has been shown to play a major role in obtaining the doubly differential cross sections (DDCS) for electron ionization. In this work we properly include the dynamic screening into the CDW model showing its influence over the ionization DDCS for several collision systems.
