RELATIVISTIC FORMALISM OF ACCOUNTING NUCL EON FINAL-STATE INTERACTIONEFFECTS IN E(-)-]E(-)+N+P REACTION .1. UNPOLARIZED PARTICLES(D)

The effects of the nucleon final state interaction (FSI) in the c(-) d --> e(-) + n + p reaction are taken into account using the method o f unitarization of the multipole amplitudes in impulse approximation. In this approach the modulus of the final multipole amplitude of the g amma + d --> n + p process (gamma* is the virtual photon) is determin ed by the relativistic version of impulse approximation and the phase of this amplitude coincides with the corresponding NN-scattering phase . The suggested unitarization procedure of the gamma + d --> n + p re action amplitude does not violate the condition of the electromagnetic current conservation for gamma + d --> n + p. Such method of account ing the FSI effects permits avoiding the restrictions of the nonrelati vistic models used for the description of the e(-) + d --> e(-) + n p reaction connected with the usage of tile Schrodinger equation, NN-p otentials and also with the choice of the nonrelativistic operator of the nucleon and pion electromagnetic interaction. The comparison of av ailable experimental data about d(e,e'p)n reaction under different kin ematical conditions with the model predictions has been carried out.
