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.
