The modified Coulomb-Born approximation model is applied to calculate the fully differential cross section (FDCS) for single ionization of helium by 100 MeV/amu C6+ impact. We study the influence of the internuclear interaction on the FDCS in the scattering plane and the perpendicular plane. Comparisons are made with absolute experimental data and the 3DW results and we find that our calculations with (without) the internuclear interaction yield excellent agreement with experiments for the small (large) momentum transfer. Accordingly, we discuss the contributions of distortion effects to the FDCS both in the scattering plane and the perpendicular plane. It turns out that the distortion effects become significantly important with increasing momentum transfer.
