Structure of to Light Germanium Isotopes in the Framework of the IBM-3


The nuclear level structure of Ge64-70 is analyzed taking into account the experimental information available, with respect to symmetry of IBM-3. The level energies, electric quadrupole reduced transition probability B(E2), magnetic dipole reduced transition probability B(M1), interband B(E2) ratios and multipole mixing ratios δ(E2/M1)are compared with available data. The adopted level schemes and the mixed symmetry states properties are discussed in the framework of isospin symmetry.
