Resumen
We report a measurement of the neutron detection efficiency for an array of neutron detectors behind a lead-steel wall consisting of 10.16 cm thick lead bricks sandwiched between 3.18 cm steel plates. The neutron detection efficiency ε was obtained from the ratio of coincidence to single-arm proton cross sections using the γ + 21H → p + n reaction. Knowledge of the neutron detection efficiency was necessary to extract the cross section for the exclusive 2H(e,e′n)1H reaction, which we used to obtain the elastic magnetic form factor Gnm of the neutron. The measurements for three different neutron energies were carried out at the MIT-Bates Linear Accelerator Center with an incident electron beam energy of 254 MeV.
