Abstract：
High-spin states in doubly odd ¹⁷⁰Re have been populated and investigated using ¹⁴²Nd( ³²S,1p3nγ) ¹⁷⁰Re reaction at 166MeV bombarding energy. One rotational band in ¹⁷⁰Re has been identified for the first time in the present study. The band has been assigned to be built on the πh _11/2⊙νi _13/2configuration according to their quasiparticle alignment, signature splitting, level spacing systematics, as well as the existing knowledge in neighboring nuclei. The result extends the high-spin studies of A=170 odd-odd nuclei to the currently lightest rhenium isotope.
