A gamma gamma angular correlation experiment investigating the nucleus Au-193 is presented. In this work the level scheme of Au-193 is extended by new level information on spins, multipolarities and newly observed states. The new results are compared with theoretical predictions from a general Interacting Boson Fermion Model (IBFM) calculation for the positive-parity states. The experimental data is in good agreement with an IBFM calculation using all proton orbitals between the shell closures at Z = 50 and Z = 126. As a dominant contribution of the d(3/2) orbital to the wave function of the lowest excited states is observed, a truncated model of the IBFM using a Bose-Fermi symmetry is applied to the describe Au-193. Using the parameters of a fit performed for Au-193, the level scheme of Pt-192, the supersymmetric partner of Au-193, is predicted but shows a too small boson seniority splitting. We obtained a common fit by including states observed in Pt-192. With the new parameters a supersymmetric description of both nuclei is established. (C) 2013 Elsevier B.V. All rights reserved.
