In this work we present fully differential cross sections (FDCSs) calculations using post and prior versions of CDW-EIS theory for helium single ionization by 100 MeV C6+ amu-1 and 3.6 MeV amu -1 Au24+ and Au53+ ions. We performed our calculations for different momentum transfer and ejected electron energies. The influence of internuclear potential on the ejected electron spectra is taken into account in all cases. We compare our calculations with absolute experimental measurements. It is shown that prior version calculations give better agreement with experiments in almost all studied cases.
