AMS Measurement of super(53)Mn at CIAE

The long-lived isotope super(5)3n cosmogenically produced in situ is a very useful indicator for geochronological dating. A new super(53)Mn accelerator-mass-spectrometry (AMS) measurement method is developed based on the HI-13 Tandem Accelerator and Delta]E-Q3D detection system at China Institute of...

Description
Summary:The long-lived isotope super(5)3n cosmogenically produced in situ is a very useful indicator for geochronological dating. A new super(53)Mn accelerator-mass-spectrometry (AMS) measurement method is developed based on the HI-13 Tandem Accelerator and Delta]E-Q3D detection system at China Institute of Atomic Energy. The performance of super(5)3r isobar separation and suppression is tested by a series of super(53)Mn standards and commercial MnO samples. The results show that the Delta]E-Q3D detection system brought about an overall suppression factor of more than 10 super(7)for the interfering isobar super(53) Cr
