利用能量为１７０ＭｅＶ左右的３６Ａｒ重离子束轰击９６Ｒｕ和１０６Ｃｄ浓缩同位素靶，分别生成缺中子同位素１３０Ｎｄ和１４０Ｔｂ．借助氦喷嘴带传输系统，用 Ｘ－γ和 γ－γ符合方法，分离鉴别了这两种核素，并进一步测定了它们的衰变性质．得到１３０ Ｎｄ的半衰期为（１３± ３）ｓ，首次建议了它的ＥＣ／β＋衰变纲图，推测了其子核１３０Ｐｒ的基态和低位能级的自旋宇称．修订了１４０Ｔｂ的原有极简单的ＥＣ／β＋衰变纲图并指认１４０Ｔｂ的基态自旋宇称为７＋．
The 36Ru and 106Cd concentrated isotope targets were bombarded with a 36 Ar heavy ion beam with an energy of about 170 MeV to generate missing neutron isotopes 130Nd and 140Tb, respectively. With helium nozzle band transmission system, X-γ and γ-γ coincidence method was used to separate and identify the two nuclides, and further determine their decay properties. The half-life of 130 Nd was obtained for 13 ± 3 s. For the first time, its EC / β + decay scheme was proposed, and the spin parity of 130Pr at its ground state and lower energy level was deduced. The original simple EC / β + decay scheme of 140Tb was revised and the ground state spin of 140Tb was identified as 7+.
