Soft-Rotator Model and Coupled-Channels Approach for Consistent Description of the Nuclear Collective Levels and Their Excitation by Nucleons

Abstract

Coupled-channels optical model approach built on the wave functions of the soft-rotator nuclear Hamiltonian is applied for the self-consistent analyses of the low-lying collective nuclear level structure and nucleon interaction with even-even nuclei in a wide A- mass region. It succeeds to describe available experimental data and B(Eλ) γ - transitions with reasonable accuracy. Along with the account of the global optical potential form and relativistic kinematics, present method was proved to be a powerful tool for studies of nucleon-induced reaction data.
