“…In order to measure 59 Ni and 63 Ni at CIAE AMS lab, the method, named DE-Q3D, was developed for effective suppression of isobaric interferences. This method was successfully used for the measurements of 32 Si and 53 Mn [14,15]. In this paper, the details for measuring 59 Ni and 63 Ni by using the DE-Q3D technique are presented.…”
