U(6/12) Dynamical Supersymmetry in 171,172Yb

The U(6/12) dynamical supersymmetry has been discussed within the framework of the inter-acting boson-fermion model, which describes collective states in odd-mass nuclei. In this work, theSU(3)limitofU(6/12)supersymmetryhasbeenconsideredtoexplainthecollectiveproperties of deformed nuclei, with the focus on identical bands in neighboring even-even and odd-A nuclei. The E2 transition rates between low-lying states and the electric quadrupole moments are given in closed form in the SU(3) limit of the U(6/12) symmetry. The present results are applied to the ground-state bands in 171,172Yb and are compared with experimental data. KCI Citation Count: 0
