Elastic and inelastic neutron scattering

WebThe observed angular distribution data of deuteron elastic and inelastic scattering from 58Ni at 170 MeV, 70,72Ge, 90Zr, 116Sn at 171 MeV and 208Pb at 86 MeV are analyzed within the optical model framework. The real and imaginary parts of the optical potentials were calculated using the double folding procedure with a B3Y-Fetal effective interaction. Neutrons undergo many types of scattering, including both elastic and inelastic scattering. Whether elastic or inelastic scatter occurs is dependent on the speed of the neutron, whether fast or thermal, or somewhere in between. It is also dependent on the nucleus it strikes and its neutron cross section.
