~(36)Cl AMS Measurement and Its Application
-
摘要: 长寿命核素~(36)Cl的半衰期为3.01×10~5a,广泛分布于自然界中.加速器质谱是目前测量~(36)Cl的最灵敏的方法.介绍了~(36)Cl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~(36)Cl的探测方法及其特点,综述了各实验室利用~(36)Cl在相关领域开展的工作及所取得的成果.Abstract: The distribution of long-lived isotope ~(36)Cl(T_(1/2)=3.01×10~5 a)is widely spread in the world.Accelerator mass spectrometry(AMS)is presently the most sensitive method for the measurement of ~(36)Cl.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 ~(36)Cl in various laboratories around the world is reviewed.
