Soft-rotator model and coupled-channels approach for consistent description of the nuclear collective levels and their excitation by nucleons

Soukhovitskij, E. Sh.*; Chiba, Satoshi

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 - mass region. It succeeds to describe available experimental data and - 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.
