Scattering of 10.4 MeV polarized neutrons from bismuth and lead between 2° and 65°

Abstract

The polarization and differential cross sections for the scattering of 10.4 MeV neutrons from lead and bismuth are measured from 1.5\ifmmode^\circ\else\textdegree\fi{} to 65\ifmmode^\circ\else\textdegree\fi{}. No significant differences are found between the polarizations in the scattering at small angles in contrast to the situation reported at 2.45 MeV. The data over the complete angular range are reproduced using a standard optical potential with the addition of the long-range interaction between the neutron magnetic moment and the nuclear Coulomb field.
