Measurements of GEn/GMn from the 2H(vece,e'vecn)1H Reaction to Q2=1.45 (GeV/c)2
Abstract
We report new measurements of the ratio of the electric form factor to the magnetic form factor of the neutron, GEn/GMn, obtained via recoil polarimetry from the quasielastic 2H(vece,e'vecn)1H reaction at Q2 values of 0.45, 1.13, and 1.45 (GeV/c)2 with relative statistical uncertainties of 7.6 and 8.4% at the two higher Q2 points, which were not reached previously via polarization measurements. Scale and systematic uncertainties are small.
