Abstract
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
