The reaction H-2(e,e(')p)n has been studied with full kinematic coverage for photon virtuality 1.75 < Q(2)< 5.5 GeV2. Comparisons of experimental data with theory indicate that for very low values of neutron recoil momentum (p(n)< 100 MeV/c) the neutron is primarily a spectator and the reaction can be described by the plane-wave impulse approximation. For 100 < p(n)< 750 MeV/c, proton-neutron rescattering dominates the cross section, while Delta production followed by the N Delta -> NN transition is the primary contribution at higher momenta.

Abstract
The reaction H-2(e,e(')p)n has been studied with full kinematic coverage for photon virtuality 1.75 < Q(2)< 5.5 GeV2. Comparisons of experimental data with theory indicate that for very low values of neutron recoil momentum (p(n)< 100 MeV/c) the neutron is primarily a spectator and the reaction can be described by the plane-wave impulse approximation. For 100 < p(n)< 750 MeV/c, proton-neutron rescattering dominates the cross section, while Delta production followed by the N Delta -> NN transition is the primary contribution at higher momenta.
