Search for decoupled bands in Odd-Odd ~(174)Re

摘要

An effort has been made to search for the decoupled bands in odd-odd ~(174)Re via the ~(159)Tb(~(20)Ne, 5nγ) ~(174)Re 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] direct X v1/2~-[521] and π1/2~-[541] direct X vi_(13/2), respectively, according to the characteristics of band structures in this mass region. Another band with strongly coupled character is also reported.
