| Abstract: | Differential neutron elastic-scattering cross sections of elemental silver were measured from 1.5 → 10 MeV at scattering angles distributed between ≈17° and 160°. Cross sections for ten inelastically scattered neutron groups were determined, corresponding to observed excitations of 328 ± 13, 419 ± 50, 748 ± 25, 908 ± 26, 1150 ± 38, 1286 ± 25, 1507 ± 20, 1623 ± 30, 1835 ± 20, and 1944 ± 26 keV, all of which were composites of contributions from the two isotopes 107Ag and 109Ag. The experimental results were interpreted in terms of the spherical-optical and rotational and vibrational coupled-channels models. |
