Abstract
The differential cross sections and polarizations of neutrons elastically scattered by U, Th, Pb, Au, W, and Cd have been measured for scattering angles between 1.75\ifmmode^\circ\else\textdegree\fi{} and 15\ifmmode^\circ\else\textdegree\fi{}. The range of neutron energies covered is from 0.6 to 1.6 MeV. These data show no evidence for any anomalous long-range neutron-nucleus interaction. The data are used to evaluate an upper limit for the absolute value of the real part of the forward-scattering amplitude at each energy for each of the above scattering samples. The polarization of neutrons that emerge at 51\ifmmode^\circ\else\textdegree\fi{} relative to the proton-beam direction in the $^{7}\mathrm{Li}(p, n)^{7}\mathrm{Be}$ reaction (the neutron-source reaction) is determined by use of these small-angle results for proton energies between 2.47 and 3.55 MeV. Some of the advantages of the use of small-angle neutron scattering as a polarization analyzer are discussed.
