Collective band inHg193withEx≥5.7 MeV

The nucleus ${}_{}{}^{193}{}_{}{}^{}\mathrm{Hg}$ was populated in the reaction ${}_{}{}^{176}{}_{}{}^{}\mathrm{Yb}$ ${(}^{22}$Ne,5n) at the incident energy E${(}^{22}$Ne)=110 MeV. Reaction γ rays were detected with a Ge-detector array. A new ‘‘collective’’ structure was observed at ${\mathit{E}}_{\mathit{x}}$>5.7 MeV. The states of the structure extend from I≥47/2 to I+10, and they decay with competing dipole and quadrupole transitions. The structure is populated very strongly in this reaction: the lowest member is produced with ∼20% of the ${}_{}{}^{193}{}_{}{}^{}\mathrm{Hg}$ cross section.
