Abstract:

High\|spin states in ¹⁶⁸Lu have been studied via the ¹⁵⁴Sm(¹⁹F,5n)¹⁶⁸Lu reaction at a beam energy of 94 MeV. In addition to the previously known bands in ¹⁶⁸Lu, 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. 
