摘要
利用离线γ能谱法,在由25MeV/A40Ar+Se反应制备的多种示踪剂中共鉴别了24种元素的47种放射性核素。其中寿命最长的核素是22Na(T1/2=22780h),寿命最短的核素是81gRb(T1/2=4.58h)。
A kind of multitracer has been prepared from the interaction of selenium with 25MeV/A 40 Ar ions. By using off-line gamma ray spectrometry, it is identified that the multitracer contain 47 kinds of radioactive nuclides belonging to 24 elements. The nuclide with the longest half-life is 22 Na and that with the shortest half-life is 81g Rb。
