Superdeformation and shape coexistence in 136Pm

Significant features of the microscopic structure of superdeformed bands are described by means of occupation of high-N, high-j intruder orbital, which are brought down in energy close to the Fermi level at large deformation and high rotational frequency. Their excitation energies relative to the Fermi level are found to decrease rapidly with increasing deformation and rotational frequency. In the present work, the detailed studies on superdeformation and shape coexistence in the nucleus 136Pm (A≈ 130 region) is discussed using rotational energy and dynamical moment of inertia which is compared with the experimental data also
