High-spin band structure ofTl192

High-spin states in ${}_{}{}^{192}{}_{}{}^{}\mathrm{Tl}$, excited through the ${}_{}{}^{181}{}_{}{}^{}\mathrm{Ta}$(${}_{}{}^{18}{}_{}{}^{}\mathrm{O}$,$7n$) and ${}_{}{}^{181}{}_{}{}^{}\mathrm{Ta}$(${}_{}{}^{16}{}_{}{}^{}\mathrm{O}$,$5n$) reactions, were studied using in-beam $\gamma$-ray spectroscopic techniques. Excitation functions, activity spectra, $\gamma$-ray angular distributions, and multidimensional coincidences were measured. The strongly Coríolis-distorted $\tilde{\pi }{h}_{\frac{9}{2}}\times \tilde{\nu }{i}_{\frac{13}{2}}$ two-quasiparticle band already known in the heavier ${}_{}{}^{194,196,198}{}_{}{}^{}\mathrm{Tl}$ isotopes has also been found in this case based on an $I^{\pi }=8^{-}$ isomeric state at 250.6 keV above the known long-lived $7^{+}$ level. Trends already noted in the other Tl isotopes and also predicted by two-quasiparticle plus-rotor model calculations are confirmed thus reinforcing such a theoretical description.
