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）。
Using off-line gamma spectroscopy, 47 radionuclides of 24 elements were identified among the various tracers prepared by the 25MeV / A40Ar + Se reaction. The nuclide with the longest life span was 22Na (T1 / 2 = 22780h), and the shortest lived nuclide was 81gRb (T1 / 2 = 4.58h).
