The Electric Form Factor of the Neutron via Recoil Polarimetry to Q2 = 1.47 (GeV/c)2

The Jefferson Laboratory E93‐038 collaboration conducted measurements of the ratio of the electric form factor to the magnetic form factor of the neutron, GEn/GMn, via recoil polarimetry from the quasielastic 2H(e,e′n)1H reaction at three values of Q2 [viz., 0.45, 1.15, and 1.47 (GeV/c)2] in Hall C of the Thomas Jefferson National Accelerator Facility. The preliminary results for GEn at Q2 = 0.45 and 1.15 (GeV/c)2 are consistent with the Galster parameterization; however, the preliminary result for GEn at Q2 = 1.47 (GeV/c)2 lies slightly above the Galster parameterization.
