The reaction H2(e,e′p)n has been studied with full kinematic coverage for photon virtuality 1.75<Q2<5.5GeV2. Comparisons of experimental data with theory indicate that for very low values of neutron recoil momentum (pn<100MeV/c) the neutron is primarily a spectator and the reaction can be described by the plane-wave impulse approximation. For 100<pn<750MeV/c, proton-neutron rescattering dominates the cross section, while Δ production followed by the NΔ→NN transition is the primary contribution at higher momenta.
