Measurement of the Electric Form Factor of the Neutron at Q^2 = 0.3-0.8 (GeV/c)^2
The electric form factor of the neutron, G_En, has been measured at the Mainz
Microtron by recoil polarimetry in the quasielastic D(e_pol,e'n_pol)p reaction.
Three data points have been extracted at squared four-momentum transfers Q^2 =
0.3, 0.6 and 0.8 (GeV/c)^2. Corrections for nuclear binding effects have been
applied.Comment: 9 pages, 7 figures, 2 tables. Accepted for publication in EPJ
Measurement of the asymmetries in 3(¯e, e′p)d and 3(¯e, e′p)np
Abstract.: The electron target asymmetries A || and A⊥ with target spin parallel and perpendicular to the momentum transfer \ensuremath{\boldsymbol{q}} were measured for both the two- and three-body breakup of 3He in the 3 (¯e, e'p)-reaction. Polarized electrons were scattered off polarized 3He 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 breaku
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
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
