  The (ed -> enp) process in the frame of the Bethe-Salpeter approach with a
separable kernel of the Nucleon-Nucleon (NN) interaction was considered. This
conception keeps the covariance of description of the process. Special
attention was devoted to a contribution of the D-states of the deuteron in the
cross section of the electrodisintegration. It was shown that the spectator
particle (neutron) plays an important role. The factorization of a cross
section of this reaction in the impulse approximation was checked by analytical
and numerical calculations.
