High-Precision Studies Of The He-3(E, E ' P) Reaction At The Quasielastic Peak

Precision studies of the reaction He-3(e,e'p) using the three-spectrometer facility at the Mainz microtron MAMI are presented. All data are for quasielastic kinematics at \(q) over right arrow\ = 685 MeV/c. Absolute cross sections were measured at three electron kinematics. For the measured missing momenta range from 10 to 165 MeV/c, no strength is observed for missing energies higher than 20 MeV. Distorted momentum distributions were extracted for the two-body breakup and the continuum. The longitudinal and transverse nature of the cross sections is well described by a widely used prescription of the off-shell electron-nucleon cross section. The results are compared to modern three-body calculations and to previous data.
