Differential cross sections and analyzing powers for neutron elastic scattering fromY89between 8 and 17 MeV

Abstract
Differential cross sections and analyzing powers for neutron elastic scattering from Y89 have been measured at energies from 8 to 17 MeV using a neutron time-of-flight facility. The data have been analyzed with the spherical optical model and excellent representations are achieved at all energies with the derived optical potential parameters, which were constrained to vary linearly with energy. Comparisons have been made to two previously reported global spherical optical models as well.
