A polarized target measurement of the electric form factor of the neutron at jlab

tric form factor of the neutron GnE through quasielastic ~d(~e, e′n)p scattering using a longitudinally polarized electron beam and a frozen polarized 15ND3 target. The knocked out neutrons were detected in a segmented plastic scintillator detector in coincidence with the scattered electrons. The GnE was extracted by comparing the experimental beam–target asymmetry with full theoretical calculations based on different values of GnE. Preliminary results of the Fall 2001 run are reported.
