Abstract: The observed variation of hexadecupole deformation parameter P4 with mass number A in rare-earth and actinide nuclei is studied in the sdg interacting boson model (IBM) using single j-shell Otsuka-Arima-Iachello mapped and IBM-2 to IBM-1 projected hexadecupole transition operator together with SU,dg(3) and SU,dg(5) coherent states. The SU,dg(3) limit is found to provide a good description of data.PACS number(s): 21.10. Ky, 21.60.Fw, 21.10.Gv, 27.70.+ q Coulomb excitation, electron scattering, Coulomb/ nucle… Show more

Properties of the four rotation bands, 157 Er(1,2) and 158 Er(1,2), at ultrahigh spin are investigated within the supersymmetry scheme including many-body interactions and possessing the SO(5) (or SU( 5)) symmetry on the rotational symmetry. Quantitatively good results of the γ-ray energies and the dynamical moments of inertia in the rotation bands in 157 Er and 158 Er at ultrahigh spin are obtained. We theoretically predict that the competition between the anti-pairing and pairing effects may exist in 157 Er(1,2) and 158 Er(2) bands states. In 158 Er(1) band state, the favourepairing effects may exist and the SO(5) (or SU( 5)) symmetry play a dominant role. There may be sphere coexisting with headecupole deformed in 158 Er(1) rotation band state.

The hexadecapole deformation parameter p4 of the rare-earth and actinide nuclei is investigated in the framework of the sdg interacing boson model. An explicit relation between the geometric hexadecapole deformation parameter ,& and the intrinsic deformation parameters ~4 , ~2 are obtained. The deformation parameters p4 of the rare-earths and actinides are determined without any free parameter. The calculated results agree with experimental data well. It also shows that the S U ( 5) limit of the sdg interacting boson model can describe the /34 systematics as well as the S U ( 3 ) limit.
