Charge Form Factor of the Neutron from the Reaction {sup 2} {rvec H}({rvec e},thinspe{prime} 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[sup V] [sub ed] was measured for the reaction [sup 2] H [rvec e] ([rvec e], e [prime] n) p at a four-momentum transfer squared of 0.21 (GeV/c)[sup 2] from which a value for the charge form factor of the neutron was extracted.
