在中国原子能科学研究院H-13串列加速器上,通过重离子核反应~(130)Te(~9Be,5n)与在束γ谱的实验技术,对A=130缺中子核区的~(134)Ba核的高自旋态进行了研究,建立了~(134)Ba核的新的能级纲图,最高自旋态扩展到20(?)．除验证了以前报道的大部分能级与跃迁外,将基带的能级扩展到10~+,同时发现了基于10~+同质异能态以上的众多的能级与跃迁．对实验结果的系统学分析表明,10~+同质异能态为yrast陷阱,起源于两中子组态,可能具有γ≈-120°的长椭形状,在其以上的能级表现出很强的单粒子性,具有复杂的结构．基带中观测到明显的集体回弯现象,推转壳模型的计算表明,此集体回弯是由一对中子的顺排所致,TRS计算表明,随着转动频率的增加,核的形状发生明显的变化,基带中在中子顺排后核具有γ≈-60°的扁椭形状．
At the H-13 tandem accelerator of China Institute of Atomic Energy, the (~ (9) Be (5n)) and γ 134) Ba spin nuclei were studied. A new energy level scheme of ~ (134) Ba nuclei was established, and the highest spin state was extended to 20 (?). In addition to verifying most of the previously reported energy levels and transitions, the energy levels of the base band are extended to 10+, while numerous energy levels and transitions based on 10+ isomorphisms are found. The systematic analysis of the experimental results shows that the 10 ~ + isomorphism is a yrast trap, originating from the two neutron configurations and possibly having an ellipsoidal shape of γ ≈ -120 ° and exhibiting a very high energy level above it Strong single particle, with complex structure. The obvious collective bend-back phenomenon was observed in the baseband. The calculation of the shell model shows that the collective bending is caused by the alignment of a pair of neutrons. The TRS calculation shows that the shape of the nucleus occurs as the rotation frequency increases Significant changes in the baseband in the neutron aligned nuclear with γ ≈ -60 ° oblate shape.
