Abstract：
Accelerator mass spectrometry has ultra-high sensitivity and can be used to detect extremely low impurity contents in samples. ¹⁰Be is a cosmogenic nuclide. As a tracker, it has been widely applied to earth, environmental and cosmographic sciences. ¹⁰Be is a pure β emitter with low end-point energy and long half-life.Therefore ¹⁰Be formation cross section can hardly be determined by the method of measuring the radioactivity of the product nucleus. This article describes a method to determine 10Be formation cross section by AMS technique and discusses the possible applications of AMS to other rare event measurements in nuclear physics.
