Nuclear Level Structure, B(E2) Gamma-transitions and Nucleon Interaction Data for 56Fe by a Unified Soft-rotator Model and Coupled-Channels Framework.

The soft-rotator model (SRM) and a coupled-channels method based on the coupling scheme built on the wave functions of the SRM were applied for a consistent analysis of the nuclear level structure, B(E2) and the nucleon interaction data of Fe-56. The model could describe the experimental collective levels of Fe-56 up to the excitation energy of 5.5 MeV successfully. Relativistic kinematics and global optical potential form, consistent with nuclear matter theory and Dirac phenomenology, were used in coupled-channels optical model approach to overcome problems left in our previous work. The available nucleon interaction experimental data up to 160MeV and B(E2) gamma-transitions were described satisfactorily.
