  The two-body knock-out reaction 4He(e,e'd)d is calculated at various momentum
transfers. The full four-nucleon dynamics is taken into account microscopically
both in the initial and the final states. As NN interaction the central
MT-I/III potential is used. The calculation shows a strong reduction of the
coincidence cross section due to the final state interaction. Nonetheless the
theoretical results exhibit a considerable overestimation of the experimental
cross section at lower momentum transfer. Comparisons with other, less
complete, calculations suggest that consideration of a more realistic ground
state might not be sufficient for a good agreement with experiment, rather a
more realistic final state interaction could play an essential role.
