Measurement of the Electric Form Factor of the Neutron through d-vector(e-vector, e'n)p
We report the first measurement using a solid polarized target of the neutron electric form factor G{sup n}{sub E} via d-vector(e-vector, e'n)p. G{sup n}{sub E} was determined from the beam-target asymmetry in the scattering of longitudinally polarized electrons from polarized deuterated ammonia ({sup 15}ND{sub 3}). The measurement was performed in Hall C at Thomas Jefferson National Accelerator Facility in quasifree kinematics with the target polarization perpendicular to the momentum transfer. The electrons were detected in a magnetic spectrometer in coincidence with neutrons in a large solid angle segmented detector. We find G{sup n}{sub E} = 0.04632{+-}0.00616(stat){+-}0.00341(syst) at Q{sup 2} = 0.495 (GeV/c){sup 2}.
