Abstract：
High spin states in ¹⁷⁴Re have been studied via the ¹⁵⁹Tb ( ²⁰Ne, 5nγ) ¹⁷⁴Re 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 band on the л1/2 ^－[541]⊙v1/2 ^－[521] configuration. Other two bands with semidecoupled and strongly coupled characters have been found and their quasiparticle configurations are qualitatively discussed.
