Measurement of the Charge Form Factor of the Neutron GEn from d⃗(e⃗,e′n)p at Q2 = 0.5 and 1.0 (GeV/c)2

We determined the electric form factor of the neutron GEn via the reaction d(e,e′n)p using a longitudinally polarized electron beam and a frozen polarized 15ND3 target at Jefferson Lab. The knocked out neutrons were detected in a segmented plastic scintillator in coincidence with the quasi‐elastically scattered electrons which were tracked in Hall C’s High Momentum Spectrometer. To extract GEn, we compared the experimental beam‐target asymmetry with theoretical calculations based on different GEn models. We report the preliminary results of the fall 2001 run at Q2 = 0.5 and 1.0 (GeV/c)2.
