36Cl AMS Measurement and Its Application
-
摘要: 长寿命核素36Cl的半衰期为3.01×105 a, 广泛分布于自然界中。 加速器质谱是目前测量36Cl的最灵敏的方法。 介绍了36Cl的样品制备及加速器质谱测量方法, 重点描述了基于小型化加速器质谱发展起来的测量36Cl的探测方法及其特点, 综述了各实验室利用36Cl在相关领域开展的工作及所取得的成果。 The distribution of longlived isotope 36Cl (T1/2=3.01×105 a) is widely spread in the world. Accelerator mass spectrometry(AMS) is presently the most sensitive method for the measurement of 36Cl. The sample preparation and AMS measurement procedure are briefly introduced. The detection methods based on the “small” AMS are also introduced, as well as their performance. The research progress on applications of 36Cl in various laboratories around the world is reviewed.Abstract: The distribution of longlived isotope 36Cl (T1/2=3.01×105 a) is widely spread in the world.
