Evidence for High-Momentum Enhancement in the Exclusive 3He(e,e'p)   Reaction Below the Quasi-Elastic Peak
  New, high-precision measurements of the 3He(e,e'p) reaction using the A1 collaboration spectrometers at the Mainz microtron MAMI are presented. These were performed in parallel kinematics at energy transfers below the quasi-elastic peak, and at a central momentum transfer of 685 MeV/c. Cross sections and distorted momentum distributions were extracted and compared to theoretical predictions and existing data. The longitudinal and transverse behavior of the cross section was also studied. Sizable enhancements of the cross sections for missing momenta larger than 100 MeV/c as compared to Plane Wave Impulse Approximation were observed in both the two- and three-body breakup channels.
