Abstract

Accelerator mass spectrometry (AMS) measurement of59Ni has been established at CIAE with the HI-13 tandem accelerator and the recently developed ΔE-Q3D detection system.59Ni standard and commercial NiO samples were measured to check the performance of the ΔE-Q3D detection system on59Ni isobar separation and suppression. An overall suppression factor of about 107for the interfering isobar59Co resulting in detection sensitivity as low as 3.8 × 10-13atomic ratio (59Ni/Ni) has been obtained. Based on these techniques, the AMS measurement method of59Ni with high sensitivity is developed. © 2013 Chinese Physical Society and the Institute of High Energy Physics of the Chinese Academy of Sciences and the Institute of Modern Physics of the Chinese Academy of Sciences and IOP Publishing Ltd. © 2013 Chinese Physical Society.
