The soft-rotator model (SRM) and a coupled-channels method based on the oupling scheme based on the wave functions of the SRM were applied for a self-consistent analyses of the nuclear level structure, B(E2) and the nucleon interaction data of Fe. The model could describe the experimental collective levels of Fe up to the excitation energy of 5.5 MeV successfully. Relativistic kinematics and global optical potential form, consistent with the shell model, dispersion relationship 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) - transitions were described satisfactorily.
