摘　　要：通过对^(252)Cf 自发裂变所产生的瞬发γ谱的实验研究,首次建立了^(141)Xe、^(152)Ce、^(153)Nd 及^(160)Sm 4个极端丰中子核的能级图,最高自旋态可达16^+.对这4个核的能级结构特性进行了讨论.The level schemes of neutron-rich nuclei,^(141)Xe,^(152)Ce,^(153)Nd and ^(160)Sm have been established for the first time through measuring the prompt γ-rays from spontaneous fission of ^(252)Cf.The highest spin state is up to 16^+.The collective band structures in these neutron-rich nuclei are discussed.
