abstract

  • The electric form factor of the neutron at Q2=0.5 and 1.0 was determined from measurements of the beam-target asymmetry. The longitudinally polarized electron beam was scattered off a polarized frozen deuterated ammonia target. The scattered electrons were detected by the high momentum spectrometer, and the neutrons were detected by a dedicated neutron detector. The experiment provided the highest Q2 measurement to date and the most precise measurement near the maximum of GEn.
