摘　　要：通过束流能量为94MeV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.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.
