Abstract

Excited states in the extremely neutron-deficient isotope Hg172 have been established for the first time. The Ru96(Kr78,2n) reaction was employed to populate excited states in Hg172 with a cross section σ15 nb. The highly selective recoil-decay tagging (RDT) technique was used to obtain clean in-beam γ-ray spectra for Hg172. The yrast ground-state band has tentatively been established up to I=6. The data have been interpreted within the framework of total Routhian surface and quasiparticle random phase approximation calculations.
