Description
Proton-nucleus inelastic scattering is an experimental probe for excitation spectrum of the target nucleus. On the other hand, the experimental data for neutron-nucleus inelastic scattering is scarce and thus one needs a robust theoretical framework to study it. Our work uses microscopic nuclear structure calculations for spherical nuclei to obtain nucleon-nucleus scattering potentials to calculate cross sections for these processes. \
We implement Jeukenne, Lejeune, Mahaux (JLM) semimicroscopic folding approach [1,2,3] where the medium effects on nuclear interaction are parameterized in nuclear matter to obtain a local energy-dependent nucleon-nucleon interaction in a medium at positive energies. We solve the nuclear ground state using Hartree-Fock-Bogoliubov many-body method, and by approximating interaction between nucleons within a nucleus as Gogny D1M potential [4]. The vibrational excited states of the target nucleus are calculated using quasi-particle random phase approximation method. We calculate the nucleon-nucleus optical and transition potentials by folding in microscopic ground state and transition densities with the JLM potential. \
We will present the results for elastic and inelastic scattering cross sections for Zr90, Zr94 and Zr96 using our scattering potentials for proton and neutron incident energies from 10-30 MeV. We will also discuss the application of this approach to computing $(n, \gamma)$ cross sections using surrogate method. \
