Cross sections and analyzing powers for fast-neutron scattering to the ground and first excited states of 58 Ni and 60 Ni


Journal Article

Differential cross sections for neutron scattering from 58Ni and 60Ni to the ground state and first excited state have been measured at 8, 10, 12 and 14 MeV. In addition, analyzing powers were measured for scattering to the same states for 58Ni at 10 and 14 MeV, and for 60Ni at 10 MeV. The data were analyzed in the framework of a coupled-channel formalism in which the vibrational model was assumed with deformed central and spin-orbit potentials. A spherical-optical-model analysis of the elastic scattering data was also performed following the coupled-channel analysis. Predictions for (p, p) and (p, p') scattering observables have been made and compared with measurements previously published. This approach permits neutron and proton deformation parameters to be deduced similarly from (n, n') and (p, p') scattering measurements for 58,60Ni. These deformation parameters are compared in the framework of the core-polarization model of Madsen, Brown and Anderson. © 1985.
