Aluminium energy degraders occupied C245700100015 slots A and B and reduced beam energy to 15-30 MeV. C245700100016 In front of the Th target a natural Ni foil was placed C245700100017 for monitoring purposes. C245700100018 DETECTOR (HPGE) Reaction products were measured using HPGe C245700100019 detector Ortec Model GMX- 35200-S. Detector diameter C245700100020 was 50 mm and its length was 53.5 mm. C245700100021 METHOD (ACTIV,CHSEP) Activation method with chemical C245700100022 separation of reaction products was used C245700100023 Proton energy at the Th target was determined from C245700100024 activity ratio 57Ni/57Co C245700100025 MONITOR 1(28-NI-0(P,X)28-NI-57,,SIG) C245700100026 2(28-NI-0(P,X)27-CO-57,,SIG) C245700100027 DECAY-MON 2(27-CO-57,271.74D,DG,122.06,0.856, C245700100028 DG,136.47,0.107) C245700100029 1(28-NI-57,35.60HR,DG,127.16,0.167, C245700100030 DG,1377.63,0.817) C245700100031 HISTORY (20201008C) Compiled by S.H.
