A complete form of the post version of the continuum distorted wave (CDW) theoryis used toinvestigare the single ionizatíon of multíelectronic atorosby fast bare heavy ion beams. The influeru:e of the non-ionized electrons on the dynamic evolution is included through a residual target potential co.nsi.dered as a non-coulomb central  potential through a GSZ parametric one. Divergences found in the transitíon amplitude containing the short-range part of the target potentia.l are avoided by considering,inthat term exclusively,an eikonal phase instead of the continuum factor as the initial channel distortion function. Inthis way, we achieve the inclusion of the interaction between the target active electron and the residual target,giving place to a more complete theory. The present analysis is supporred by comparisons withexistingexperimental electron emission spectra and other distorted wave theories.
