Abstract
We report the first measurement using a solid polarized target of the neutr on electric form factor G(E)(n) via (d) over right arrow((e) over right arr ow, e' n)p. G(E)(n) was determined from the beam-target asymmetry in the sc attering of longitudinally polarized electrons from polarized deuterated am monia ((ND3)-N-15). The measurement was performed in Hall C at Thomas Jeffe rson National Accelerator Facility in quasifree kinematics with the target polarization perpendicular to the momentum transfer. The electrons were det ected in a magnetic spectrometer in coincidence with neutrons in a large so lid angle segmented detector. We find G(E)(n) = 0.04632 +/- 0.00616(stat) /- 0.00341(syst) at Q(2) = 0.495 (GeV/c)(2).
