用极难分离的Ｇｄ、Ｅｕ为对象，研究确定分离最佳条件后，再配置大量Ｇｄ和少量Ｔｂ和Ｅｕ的混合物，将混合物先分别用１６０Ｔｂ和１５２、１５４Ｅｕ标记，求得Ｔｂ和Ｅｕ相对于Ｇｄ的排代位置，再将混合物用堆照产物１５４、１５９Ｇｄ标记钆，进行分离。结果表明Ｇｄ中所含少量的Ｅｕ和Ｔｂ能够和钆很好地分开，获得纯的放射性１５４、１５９Ｇｄ。 With the extremely difficult separation of Gd, Eu as the object, to study to determine the best separation conditions, and then configure a large amount of Gd and a small amount of Tb and Eu mixture, the mixture were first marked with 160Tb and 152,154Eu, Tb and Eu obtained Gd displacement position, and then the mixture of 154,159Gd with the stack labeled gadolinium, were separated. The results show that a small amount of Eu and Tb contained in Gd can be well separated from gadolinium to obtain pure radioactive 154,159Gd.
