Abstract

The reaction ²H(e,e(')p)n has been studied with full kinematic coverage for photon virtuality 1.75 < Q²< 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 NΔ → NN transition is the primary contribution at higher momenta.
