We report the first measurement using a solid polarized target of the neutron electric form factor G{sup n}{sub E} via {rvec d}({rvec e},e{prime}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}.
