围绕Z=56和N=88丰中子核区八极形变的研究

Research on Octupole Deformation in Neutron rich Nuclei around Z =56, N =88 Region

介绍了通过测量重核裂变产生的瞬发γ谱方法，对围绕Ｚ＝５６、Ｎ＝８８丰中子核区高自旋态八极形变的研究，并对Ｘｅ、Ｂａ、Ｃｅ和Ｌａ等丰中子核链的八极形变特性进行了讨论．

Through study of the prompt γ rays in spontaneous fission, the octupole deformation in neutron rich Xe, Ba, Ce and La isotopes around Z =56, N =88 region was assigned. The properties of the octupole deformation in these nuclei were also discussed.
