To avoid 3273600100023 interference from thermal neutrons, the sample was 3273600100024 wrapped with Cd foil with a thickness of 2 mm during 3273600100025 the irradiation. 3273600100026 DETECTOR (HPGE) HPGe gamma-ray spectrometer. The system has an 3273600100027 energy resolution of 1.83 keV and a relative 3273600100028 efficiency of 47% for 1.33 MeV gamma ray. 3273600100029 METHOD (ACTIV) Irradiated for ~8 hours. 3273600100030 (AMS) 59Ni/60Ni ratio determined with standard 60Ni. 3273600100031 Separately prepared at CIAE. 3273600100032 REL-REF (M,,Xiaoming Wang+,J,NIM/B,361,34,2015) 3273600100033 Details on measurement of 59Ni and 63Ni by AMS at CIAE3273600100034 MONITOR (28-NI-58(N,P)27-CO-58,,SIG) 3273600100035 (28-NI-58(N,X)27-CO-57,,SIG) 3273600100036 DECAY-MON (27-CO-58-G,70.82D,DG,810.7,0.99) 3273600100037 (27-CO-57,271.79D,DG,122.,0.856) 3273600100038 INC-SOURCE (D-T) Neutrons were produced by the T(D,n)a reaction 3273600100039 with a D beam current of about 500 uA.
