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