Аннотация

Excited states of the nucleus $^{167}\mathrm{Os}$ have been populated by the reaction $^{92}\mathrm{Mo}(^{78}\mathrm{Kr},2\mathit{pn})$. The JUROGAM $\ensuremath{\gamma}$-ray detector array has been used in conjunction with the RITU gas-filled separator and the GREAT spectrometer to observe prompt $\ensuremath{\gamma}$ rays in coincidence with recoiling fusion-evaporation residues and their subsequent decay by $\ensuremath{\alpha}$ particle emission. By correlating prompt $\ensuremath{\gamma}$ radiation with the characteristic $\ensuremath{\alpha}$ radioactivity of $^{167}\mathrm{Os}$, it has been possible to extend the level scheme for this nucleus significantly. In particular, an extension of the yrast band and four previously unobserved bands are reported. In addition, the recoil distance Doppler-shift method was used to determine a lifetime of $\ensuremath{\tau}=20(4)$ ps for The ${I}^{\ensuremath{\pi}}=17/{2}^{+}$ state in $^{167}\mathrm{Os}$. Hence, the level of collectivity and magnitude of deformation of the low spin yrast band of this nucleus is established.
