用能量为105MeV 的~(16)O束流,通过~(159)Tb(~(16)O,5nγ)~(170)Ta 反应研究了~(170)Ta的高自旋态,观察到~(170)Ta 的3个转动带,其中一个耦合带和一个半退耦带中的非优先ΔI=2转动系列是由本工作发现的.文中还讨论了这些转动带可能的准粒子组态.
The high spin states of ~ (170) Ta were investigated by ~ (159) Tb (~ (16) O, 5nγ) ~ (170) Ta reaction with a ~ ) The three rotation bands of Ta, one of the coupling bands and one of the semi-decoupling bands, have been discovered by this work. The possible quasi-particle configurations of these bands are also discussed.
