Superdeformation in {sup 191}Au
- and others
A superdeformed (SD) band has been observed in {sup 191}Au, extending this region of superdeformation below Z=80 for the first time. The experiments were carried out at the LBL 88-Inch Cyclotron using the HERA facility and the reaction {sup 186}W({sup 11}B,xn) at 78, 84, and 86 MeV. The SD is assigned to the [411]{1/2} orbital and is the first K={1/2} SD band in this region. The observed SD band has transition energies identical to those in one of the bands in {sup 191}Hg. This surprising result and the absence (or weakness) of its signature partner may be explained by the similarities in single-particle structures of a single neutron hole and a single proton hole in the {sup 192}Hg core. This may suggest that the properties of specific individual orbitals are important to understand identical bands.
