    利用重离子熔合蒸发反应159Tb (20Ne, 5n)174Re, 并通过激发函数、KX-γ和γ-γ符合测量, 研究了174Re核的高自旋态. 鉴别并指定了174Re核的一个基于π1/2-[541](×)ν1/2-[521]准粒子组态上的双退耦带. 还发现了两个分别具有半退耦特征和强耦合特征的转动带,定性地讨论了它们的粒子组态.

    High spin states in 174 Re have been studied via the 159 Tb (20Ne, 5nγ) 174 Re reaction through excitation function, X-γ and γ-γ coincidence measurements. A stretched E2 cascade has been identified and assigned to be the doubly decoupled band based on the π1/2-[541](×)ν1/2-[521] configuration. Other two bands with semidecoupled and strongly coupled characters have been found and their quasiparticle configurations are qualitatively discussed.
