A Predictive Model of Nucleon-Nucleus Scattering Cross Sections

Abstract

Nucleon total reaction and neutron total cross sections as well as angular variables including spin observables from 25 to 300 MeV for all stable nuclei from ⁶Li to ²³⁸U have been predicted that are in good agreement with measured data. Those predictions have been made using non-local, energy dependent, and complex optical potentials in coordinate space formed by full folding of effective nucleon-nucleon interactions with realistic nuclear ground state densities. By inverse kinematics the same model prescription describes exotic (radioactive) nuclei scattering from hydrogen as a target and the results reveal the extended (neutron) distributions such nuclei can have.
