ABSTRACT: Precise data on the neutron magnetic form factor G mn have been obtained with measurements of the ratio of cross sections of D(e,e′n) and D(e,e′p) up to momentum transfers of Q 2=0.9 (GeV/c)2. Data with typical uncertainties of 1.5% are presented. These data allow for the first time to extract a precise value of the magnetic radius of the neutron.  [Show abstract] [Hide abstract]
ABSTRACT: The neutron magnetic form factor Gmn has been determined via a measurement of the ratio of cross sections D(e,e′n) and D(e,e′p). The absolute detection efficiency of the neutron detector was measured with high accuracy using tagged neutrons produced from H(n,p)n elastic scattering by means of a high intensity neutron beam. This approach minimizes the model dependence and improves upon the weakest points of previous experiments. Data in the range q2=0.2–0.8 (GeV/c)2 with uncertainties of <2% are presented.

ABSTRACT: We have measured the tensor analyzing power of d4He elastic scattering at θd = 150° in the energy range from 30 to 52 MeV. In this region the analyzing power is large, and the process can be employed as a standard to calibrate the tensor polarization of deuteron beams.  [Show abstract] [Hide abstract]
ABSTRACT: Tensor analyzing powers Axx and Ayy and vector analyzing powers Ay of the 1H(,pp)n breakup reaction at Ed = 52.1 MeV were measured in the symmetric collinear and coplanarstar kinematic configurations. The experimental results are compared with rigorous threenucleon continuum calculations using realistic nucleonnucleon potentials.  [Show abstract] [Hide abstract]
ABSTRACT: The vector analyzing power Ay for the reaction has been measured at five angles between 60° and 140° in the lab at an incident neutron energy of 67.7 MeV. The measurement is of a presision never before acheived (ΔAy ⩽ 0.01, statistical) for this observable. This precision makes possible a quantitative comparison with mesonexchange theories, thus enhancing our understanding of the role of nonnucleonic degrees of freedom.
