Study for Superdeformed Bands in A~190 Region with Quantum Group Uqp(u2) Model

  • superdeformed bands in the A~190 region are systematically analyzed by using the twoparameter expansion of quantum group Uqp(u2) Model. The calculated results of E2 transition γ ray energies are in agreement with experimental data. According to three different methods for the spin assignment of rotational bands, the spin values of the band head I0 of the yrast SD bands in 194Hg(1) and 194Pb(1) are assigned. Furthermore, the physical meaning of the nuclear softness is discussed, and these nuclear softness values of a signature partner are almost equal.

Abstract: superdeformed bands in the A~190 region are systematically analyzed by using the twoparameter expansion of quantum group Uqp(u2) Model. The calculated results of E2 transition γ ray energies are in agreement with experimental data. According to three different methods for the spin assignment of rotational bands, the spin values of the band head I0 of the yrast SD bands in 194Hg(1) and 194Pb(1) are assigned. Furthermore, the physical meaning of the nuclear softness is discussed, and these nuclear softness values of a signature partner are almost equal.
