Neutron elastic scattering from 116,118,120,122,124Sn

Abstract Accurate measurements of neutron differential elastic cross sections have been obtained from even isotopes of Sn. Data are presented for the elastic scattering of 11 MeV neutrons from 116, 118, 120, 122, 124 Sn, the elastic scattering for 24 MeV neutrons from 116, 118, 124 Sn and the neutron total cross section from 118, 120, 122, 124 Sn in the energy ranges 5.0–10.6 MeV and 20.0–26.0 MeV. The elastic scattering data are analyzed in terms of an empirical optical-model potential. The obtained optical-potential parameters are analyzed in terms of energy and isospin dependence and compared with those obtained from proton elastic scattering on even Sn isotopes.
