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