In this work, a dynamic charge is employed in the continuum distorted wave-eikonal initial state theoretical model to describe the non-Coulomb potential of the residual target for single ionization in bare ion-multielectron atom collisions. A comparison between the well-known Belkić prescription and the effective charge depending on emission angle and energy in the final residual-target continuum state is shown. The obtained results show that this effective charge improves the description of double-differential cross sections for backward emission angles over the whole emission energy range allowing the calculation of simple differential and total cross sections.
