Measurement of the asymmetries in (³He) over-right-arrow((e)over-right-arrow, e'p)d and (³He) over-right-arrow((e)over-right-arrow, e'p)np
2005
The electron target asymmetrics A(parallel to) and A(perpendicular to) with target spin parallel and perpendicular to the momentum transfer q were measured for both the two- and three-body breakup of He-3 in the He-3(e,e`p)- reaction. Polarized electrons were scattered off polarized He-3 in the quasielastic regime in parallel kinematics with the scattered electron and the knocked-out proton detected using the Three-Spectrometer Facility at MAMI The results are compared to Faddeev calculations which take into account Final-State Interactions as well as Meson Exchange Currents. The experiment confirms the prediction of a, large effect of Final-State Interactions in the asymmetry of the three-body breakup and of an almost negligible one for the two-body breakup.
