Search for decoupled bands in Odd-Odd $^{174}$Re

An effort has been made to search for the decoupled bands in odd-odd 174Re via the 159Tb(20Ne,5n γ)174Re reaction through excitation functions, K x-γ and γ-γ coincidence measurements. The doubly decoupled band and the semidecoupled one have been found in this work. Their quasiparticle configurations are proposed to be π1/2−[541] ⊗ν1/2−[521] and π1/2−[541] ⊗νi13/2, respectively, according to the characteristics of band structures in this mass region. Another band with strongly coupled character is also reported.
