| Abstract: | High-spin states in ~(168)Lu have been studied via the ~(154)Sm(~(19)F,5n)~(168)Lu reaction at a beam energy of 94 MeV.In addition to the previously known bands in ~(168)Lu, a new band was observed and assigned to the π7/2~+[404](⊕)υ5/2~-[523] ground-state configuration.Transitions through which the π7/2~+[404](⊕)υ5/2~+[642] and π9/2~-[514](⊕)υ5/2~+[642] bands decay down to lower states were established, and on this basis, spin assignments for the two bands were proposed. |
