Status of Bates experiment 85‐05: The electric form factor of the neutron from the d(e↘,e’n↘)p reaction

The Bates E85‐05 Collaboration measured the polarization of the neutron in the d(e↘,en↘)p reaction in the quasifree region with the objective of extracting the electric form factor of the neutron. Electron‐neutron coincidence spectra were obtained during 567 μA‐hours of integrated beam. We succeeded in operating a Mo/ller scattering polarimeter in the coincidence mode with a low‐duty factor accelerator in order to measure the polarization of the electron beam.
