In the present work the generalized CDW-EIS (CDW-EIS II) model is applied to study total cross sections for single electron capture involving multielectron atomic targets. The CDW-EIS II model was developed in the framework of the three-body-approximation, where a given active electron moves under a combined fields of the projectiles and the residual target considering that the other electrons remain frozen in their initial state. The interaction between the active electron and the residual target nucleus is represented by a spherical symmetric model potential in both the initial and final channels. Therefore bound and continuum target states result orthogonal wavefunctions. These wavefunctions are obtained by solving numerically one electron Schrodinger equations with Hartree-Fock-Slater model potential. We apply this approximation to the study of single electron capture from Li, Ne and Ar targets by impact of protons.
