$\gamma$γ-vibration in 198Hg

Low lying states of 198Hg have been investigated via 197Au(7Li,\alphan\gamma reaction at E_{\mathrm{beam}} = 33, 38MeV and the members of the \gammavibrational band have been identified. Results are compared with the systematic of this mass region and found in agreement. The observed band structures have been interpreted using the theoretical framework of the microscopic triaxial projected shell model (TPSM) approach and it is shown...
