Abstract

The measurements of GEn/GMn obtained via recoil polarimetry from the quasielastic 2H(e→,e′n→)1H reaction at three central Q2 values of 0.45, 1.15 and 1.47 (GeV/c)2 were reported. A beam of longitudinally polarized electrons was found to scatter quasielastically from a neutron in a 15-cm liquid deuterium target. A scattered electron was detected in the High Momentum Spectrometer (HMS) in coincidence with the recoil neutron.
