Sažetak

Leptoproduction of nucleons on nuclear targets into the backward hemisphere is studied at relativistic subasymptotic energies and momenta. Spins are neglected. The relativistic internucleon potential is extracted from the appropriate photoproduction data. Different production mechanisms are shown to work together and interfere. Calculations show that whenever rescattering is possible, it gives the bulk of the contribution, except at very high Q2. The Weizsäcker-Williams approximation is found to generally reproduce only a small part of the total cross-section. Comparison with the data for A(e,e˘p) reaction at E=2.4 GeV shows a reasonable agreement.
