摘要

Neutron-elastic- and -inelastic-scattering cross sections of elemental tin were measured from approximate to 1.5 to 10 MeV. Below 3 MeV, ten angular intervals were used distributed between approximate to 20 degrees and 160 degrees, and the incident-energy increments were approximate to 0.1 MeV. From 3 to 4 MeV, 20 angular intervals, distributed over the same angular range, were used, and the energy increments were approximate to 0.2 MeV. From 4.5 to 10 MeV the measurements were made at greater than or equal to 40 angular intervals distributed between approximate to 10 degrees and 160 degrees, and at energy increments of approximate to 0.5 MeV. Inelastically scattered neutron groups corresponding to average excitations of approximate to 1.15 and approximate to 2.27 MeV were observed. The experimental results were combined with elemental and isotopic values from the literature, to form a comprehensive data base extending to 24 MeV for physical interpretations using optical-statistical and coupled-channels models, with attention to isospin and collective effects. These physical interpretations were compared with present and previously reported results and with physical concepts. [References: 82]
