摘要：

In this work the results of an in-beam experiment on Au-195 are presented, yielding new spins, multipole mixing ratios, and new low-lying states essential for the understanding of this nucleus. The positive-parity states from this work together with compiled data from the available literature for Au185-199 are compared to Interacting Boson Fermion Model calculations employing the Spin(6) Bose Fermi symmetry. The evolution of the parameters for the tau splitting and the J splitting reveals a smooth behavior. Thereby, a common description based on the Bose Fermi symmetry is found for Au189-199. Furthermore, the calculated E2 transition strengths are compared to experimental values with fixed effective boson and fermion charges for all odd even gold isotopes, emphasizing that the Spin(6) Bose-Fermi symmetry is valid for the gold isotopes.
