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 56 Fe. The model could describe the experimental collective levels of 56 Fe 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 160 MeV and B(E2) γ -transitions were described satisfactorily.
