Optical model description of the neutron interaction with /sup 116/Sn and /sup 120/Sn over a wide energy range
Differential cross sections for neutron elastic scattering and inelastic scattering to the first 2/sup +/ and 3/sup -/ excited states have been measured at 10, 14, and 17 MeV for /sup 120/Sn and at 10 and 14 MeV for /sup 116/Sn. Analyzing powers have also been measured at 10 and 14 MeV for elastic scattering from both isotopes and at 10 MeV for inelastic scattering from /sup 120/Sn. These data have been analyzed in the framework of the coupled-channels formalism for vibrational nuclei. Previously reported neutron scattering measurements performed below 25 MeV, along with total cross-section measurements from 10 keV to 100 MeV, and s- and p-wave strength functions were also considered in the analysis in order to place additional constraints on the optical potential parameters. Neutron scattering deformations have been deduced for the quadrupole and octupole vibrations. These deformations have been compared with those derived from earlier (n,n') and (p,p') scattering measurements which were reanalyzed in the present work.
