Abstract

The soft-rotator model was employed for a consistent analysis of the collective nuclear structure, B(E2) and the nucleon (both neutron and proton) interaction with 12C and the optical potential parameters were deduced to describe the nucleon-induced cross sections up to 150 MeV. It was found that the state-dependent enhancement of the coupling strengths for various transitions as predicted by the soft-rotator model, determined from the analysis of the collective level structure, was inevitable to describe the nucleon scattering to different excited states in a unified manner. It was also recognized that inclusion of the proton scattering data is important to estimate the optical potential parameters up to high incident energies. As a consequence, the model could describe nucleon interaction data with a good accuracy up to 150 MeV, showing that the present method is a powerful tool for evaluation of nucleon-induced nuclear data, especially for the high energy libraries.
