I. Passchier et al., Charge form factor of the neutron from the reaction (2)(H)over-right-arrow((e)over-right- arrow,e ' n)p, PHYS REV L, 82(25), 1999, pp. 4988-4991
We report on the first measurement of spin-correlation parameters in quasif
ree electron scattering from vector-polarized deuterium. Polarized electron
s 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 paint. Vector-polarized deuterium was produced by an atomic bea
m source and injected into an open-ended cylindrical cell, internal to the
electron storage ring. The spin correlation parameter A(ed)(V) was measured
for the reaction 2 (H) over right arrow((e) over right arrow, e' n)p at a
four-momentum transfer squared of 0.21 (GeV/c)(2) from which a value for th
e charge form factor of the neutron was extracted.
