Abstract
An effort has been made to search for the decoupled bands in odd-odd ¹⁷⁴Re via the ¹⁵⁹Tb(²⁰Ne,5n $\gamma$ )¹⁷⁴Re reaction through excitation functions, K x- $\gamma$ and $\gamma$ - $\gamma$ coincidence measurements. The doubly decoupled band and the semidecoupled one have been found in this work. Their quasiparticle configurations are proposed to be $\pi 1/2^{-}[541]\otimes \nu 1/2^{-}[521]$ and $\pi 1/2^{-}[541]\otimes$ $\nu i_{13/2}$ , respectively, according to the characteristics of band structures in this mass region. Another band with strongly coupled character is also reported.
