The four-body modified Coulomb-Born approximation including the internuclear interaction (MCB-NN) with a full quantum-mechanical method, is applied to investigate single ionization of helium by 2 MeV/amu C6+ impact. The fully differential cross-sections (FDCS) are calculated for a variety of momentum transfers and ejected electron energies in the scattering plane. The obtained results are compared with the experimental data and the three-body distorted wave-eikonal initial state (3DW-EIS) results and we find that the magnitudes and the angular distribution of the FDCS is well reproduced by the MCB-NN theory for low ejected electron energy. Especially in the recoil region, the present MCB-NN results yield an excellent agreement with experiment.
