摘要: 使用在线同位素分离器及快带传输系统研究了缺中子稀土核137Eu的衰变性质，测量了A＝137核的γ、X单谱及γ-X、γ-γ符合谱，得到了137Eu核的半衰期为9．8s，并观测到了137Eu的一条能量为209．0keV的衰变γ线． The decay properties of neutron-deficient rare earth nucleus 137Eu have been studied by means of on-line isotope separator combined with rapid tape transport system.The products were produced by 190 MeV 36Ar bombarding on Pd target via natPd (36Ar, pxn)137Eu reactions. γ, X singles and γ-X, γ-γ coincidence spectra of the nuclei with A=137 were measured. The half-life of 137Eu is obtained to be 9. 8 s. A γ-ray with energy of 209. 0 keV for 137Eu was observed.
