Abstract
We report a measurement of the neutron detection efficiency for an arr ay of neutron detectors behind a lead-steel wall consisting of 10.16 c m thick lead bricks sandwiched between 3.18 cm steel plates. The neutr on detection efficiency epsilon was obtained from the ratio of coincid ence to single-arm proton cross sections using the gamma + H-2(1) --> p + n reaction. Knowledge of the neutron detection efficiency was nece ssary to extract the cross section for the exclusive H-2(e,e'n)H-1 rea ction, which we used to obtain the elastic magnetic form factor G(M)(n ) of the neutron. The measurements for three different neutron energie s were carried out at the MIT-Bates Linear Accelerator Center with an incident electron beam energy of 254 MeV. (C) 1998 Elsevier Science B. V.
