Abstract

We report new measurements of the ratio of the electric form factor to the magnetic form factor of the neutron, $G_{E}^{n} / G_{M}^{n}$ , obtained via recoil polarimetry from the quasielastic ${}^{2}H (\vec{e}, e^{'} \vec{n}) {}^{1}H$ reaction at $Q^{2}$ values of 0.45, 1.13, and $1.45 (G e V / c)^{2}$ with relative statistical uncertainties of $7.6 %$ and $8.4 %$ at the two higher $Q^{2}$ points, which points have never been achieved in polarization measurements.
