Abstract

Excited states in the extremely neutron-deficient isotope ${}^{172}{Hg}$ have been established for the first time. The ${}^{96}{Ru} ({}^{78}{Kr}, 2 n)$ reaction was employed to populate excited states in ${}^{172}{Hg}$ with a cross section $σ \approx 15$ nb. The highly selective recoil-decay tagging (RDT) technique was used to obtain clean in-beam $γ$ -ray spectra for ${}^{172}{Hg}$ . The yrast ground-state band has tentatively been established up to $I = 6 ℏ$ . The data have been interpreted within the framework of total Routhian surface and quasiparticle random phase approximation calculations.
