丰中子核141Xe、152Ce、153Nd 及160Sm 能级图的建立
Level Schemes in Neutron-Rich 141Xe,152Ce,153Nd and 160Sm Nuclei
【摘要】 通过对252Cf 自发裂变所产生的瞬发γ谱的实验研究,首次建立了141Xe、152Ce、153Nd 及160Sm 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.
【Abstract】 The level schemes of neutron-rich nuclei,141Xe,152Ce,153Nd and 160Sm have been established for the first time through measuring the prompt γ-rays from spontaneous fission of 252Cf.The highest spin state is up to 16+.The collective band structures in these neutron-rich nuclei are discussed.
