摘要：

通过束流能量为94 MeV的熔合蒸发反应¹⁵⁴Sm(¹⁹F,5n)¹⁶⁸Lu布居了双奇核¹⁶⁸Lu的高自旋态, 发现一条新转动带, 将其指定为建立在π7/2⁺［404］υ5/2^-［523］基态上的转动带, 并发现了π7/2⁺［404］υ5/2⁺［642］和π9/2^-［514］υ5/2⁺［642］转动带同低激发态间的连接关系, 确定了转动带的自旋.

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. 
