Popis:	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 ionisation in bare ion-multielectron atom collisions. A comparison between the well-known Belki'{c}'s prescription and the effective charge depending on emission-angle and -energy in the final residual-target continuum state is shown. The obtained results shown that this effective charge improves the description of double differential cross sections for backwards emission angles over the whole emission energy range allowing the calculation of simply differential and total cross sections.
