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.
Through the experimental study of the instantaneous γ spectrum caused by spontaneous fission of ~ (252) Cf, four extreme abundances of ~ (141) Xe, ~ (152) Ce, ~ (153) Nd and ~ (160) Sm have been established for the first time The energy level diagrams of the neutron nuclei show that the highest spin states can reach 16 ~ +. The energy level structural characteristics of these four nuclei are discussed.
