Abstract
The long-lived isotope 53Mn cosmogenically produced in situ is a very useful indicator for geochronological dating. A new 53Mn accelerator−mass-spectrometry (AMS) measurement method is developed based on the HI-13 Tandem Accelerator and ΔE−Q3D detection system at China Institute of Atomic Energy. The performance of 53Cr isobar separation and suppression is tested by a series of 53Mn standards and commercial MnO samples. The results show that the ΔE−Q3D detection system brought about an overall suppression factor of more than 107 for the interfering isobar 53Cr.
