Quantum preequilibrium multistep direct calculations for nucleon scattering on spherical and deformed nuclei: a microscopic approach

Abstract

Abstract. Preequilibrium multistep direct (MSD) double differential cross sections are calculated for medium energy inelastic neutron scattering (11-18 MeV) on 208 Pb and 238 U. A microscopic approach is used, since no adjustable parameters are involved. Cross section are expressed as a sum of DWBA transition amplitudes computed with the microscopic two-body interaction M3Y. Final target states are expressed as particle-hole excitations built from single particle states obtained within the HF+BCS theory applied with Skyrme force.
