Charge Form Factor of the Neutron from the Reaction2H→(e→,e′n)p

We report on the first measurement of spin-correlation parameters in quasifree electron scattering from vector-polarized deuterium. Polarized electrons were injected into an electron storage ring at a beam energy of 720 MeV. A Siberian snake was employed to preserve longitudinal polarization at the interaction point. Vector-polarized deuterium was produced by an atomic beam source and injected into an open-ended cylindrical cell, internal to the electron storage ring. The spin correlation parameter $A_{\mathrm{ed}}^V$ was measured for the reaction ${}^2\overrightarrow{\mathrm{H}}\left(\overrightarrow{e}{,e}^{\prime }n\right)p$ at a four-momentum transfer squared of 0.21 $(\mathrm{GeV}/c{)}^2$ from which a value for the charge form factor of the neutron was extracted.
