【摘要】 着重介绍中国原子能科学研究院的ＨＩ－１３串列加速器质谱计装置的粒子鉴别技术。该装置于１９８９年建成，到目前可以完成自然界中１０Ｂｅ、２６Ａｌ、３６Ｃｌ与１２９Ｉ的测定，测量灵敏度达到１０－１３－１０－１５（同位素比值），探测限度为１０５－１０７个原子更多还原

【Abstract】 The particle identification techniques used in the accelerator mass spectrometry (AMS) system based on the HI-13 tandem accelerator at China Institute of Atomic Energy have been introduced. With this system, 10 Be, 26 Al, 36 Cl and 129 I in natural sampls were measured with a sensitivity of 10 -13 —10 -15 (istope ratio) and a detection limit of 10 5—10 7 atoms.更多还原
