Abstract：
Accelerator mass spectrometry (AMS) measurement of ⁵⁹Ni has been established at CIAE with the HI-13 tandem accelerator and the recently developed Δ E-Q3D detection system. ⁵⁹Ni standard and commercial NiO samples were measured to check the performance of the Δ E-Q3D detection system on ⁵⁹Ni isobar separation and suppression. An overall suppression factor of about 10 ⁷for the interfering isobar ⁵⁹Co 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 of ⁵⁹Ni with high sensitivity is developed.
