{sup 2}H(e,e'p)n Reaction at High Recoil Momenta

The 2H(e,ep)n cross section was measured in Hall A of the Thomas Jefferson National Accelerator Facility near the top of the quasielastic peak (xBj = 0.964) at a four-momentum transfer squared, Q2 = 0.665 (GeV/c)2 (= 0.368GeV, W = 2.057GeV), and for recoil momenta up to 550MeV/c. The measured cross section deviates by 1-2 from a state-of-the-art calculation at low recoil momenta. At high recoil momenta the cross section is well described by the same calculation; however, in this region, final-state interactions and interaction currents are predicted to be large, and alternative choices of nucleon-nucleon potential and nucleon current operator may result in significant spread in the calculations.
