Solid tritium- 3287200100011 titanium (T-Ti) target in thickness of 2.59 mg/cm2 3287200100012 was bombarded by deuteron ions. The beam current of 3287200100013 the deuterium was up to 180 uA with a maximum energy 3287200100014 of 250 keV. 3287200100015 SAMPLE (29-CU-65,NAT=0.3083) Two natural copper and iron 3287200100016 foils with a diameter of 15 mm and a thickness of 3287200100017 0.1 mm were sandwiched between natural niobium foil 3287200100018 and zirconium foil with the same diameter. 3287200100019 The samples were placed at 40 and 60 deg angles 3287200100020 relative to the deuteron beam direction and centered 3287200100021 about the T-Ti target at a distance of about 4 cm. 3287200100022 METHOD (ACTIV) The copper samples were irradiated for about 3287200100023 50 min, cooled for about 8 min each. The gamma-ray 3287200100024 counting of reaction products in the irradiated 3287200100025 samples was done for about 30 min each. The distance 3287200100026 between the samples and the detector is 4.5 cm. 3287200100027 DETECTOR (SIBAR) In order to monitor the variation of the 3287200100028 neutron yield, accompanying alpha-particles were 3287200100029 recorded every second during irradiation period by 3287200100030 Au-Si surface barrier detector, which are placed at 3287200100031 135 deg relative the direction of deuteron. 3287200100032 (HPGE) A series of point source (22Na, 60Co, 133Ba, 3287200100033 137Cs, 152Eu, 210Pb, 241Am) of known activity were 3287200100034 used to determine the absolute photopeak efficiency 3287200100035 of a lead-shielded high purity germanium detector 3287200100036 with a relative efficiency of 68% and an energy 3287200100037 resolution of 1.82 keV at 1.33 MeV for 60Co. 3287200100038 MONITOR (26-FE-56(N,P)25-MN-56,,SIG) 3287200100039 MONIT-REF (,A.A.Filatenkov,R,INDC(CCP)-0460,2016) 3287200100040 DECAY-MON (25-MN-56,2.5789HR,DG,846.7638,0.9885) 3287200100041 CORRECTION The coincidence sum effect of cascade gamma-rays 3287200100042 generated from the investigated nuclide (1.005), 3287200100043 sample self-absorption for the specific gamma-ray 3287200100044 energy (1.002) and sample counting geometry (1.002). 3287200100045 ERR-ANALYS (ERR-T) The total uncertainties, 6% - 9% 3287200100046 (ERR-S,2.,2.5) The counting statistics 3287200100047 (ERR-1,3.,3.5) Detector efficiency 3287200100048 (ERR-2) The fluctuation of the neutron fluence 3287200100049 (MONIT-ERR) The standard cross sections 3287200100050 STATUS (TABLE,,Xianlin Yang+,J,RPC,197,110192,2022) Table 2 3287200100051 HISTORY (20241211C) Xi Tao and Jimin Wang 3287200100052 ENDBIB 50 0 3287200100053 COMMON 2 3 3287200100054 EN-RSL-HW ERR-2 3287200100055 MEV PER-CENT 3287200100056 0.2 3. 3287200100057 ENDCOMMON 3 0 3287200100058 ENDSUBENT 57 0 3287200199999 SUBENT 32872002 20241211 32153287200200001 BIB 2 2 3287200200002 REACTION (29-CU-65(N,A)27-CO-62-M,,SIG) 3287200200003 DECAY-DATA (27-CO-62-M,13.86MIN,DG,1163.5,0.705) 3287200200004 ENDBIB 2 0 3287200200005 NOCOMMON 0 0 3287200200006 DATA 5 2 3287200200007 EN DATA ERR-T MONIT MONIT-ERR 3287200200008 MEV MB MB MB MB 3287200200009 14.5 6.07 0.44 109.44 2.19 3287200200010 14.7 5.40 0.49 107.43 1.99 3287200200011 ENDDATA 4 0 3287200200012 ENDSUBENT 11 0 3287200299999 SUBENT 32872003 20241211 32153287200300001 BIB 2 2 3287200300002 REACTION (29-CU-65(N,N+A)27-CO-61,,SIG) 3287200300003 DECAY-DATA (27-CO-61,1.649HR,DG,67.4,0.847) 3287200300004 ENDBIB 2 0 3287200300005 NOCOMMON 0 0 3287200300006 DATA 5 2 3287200300007 EN DATA ERR-T MONIT MONIT-ERR 3287200300008 MEV MB MB MB MB 3287200300009 14.5 1.83 0.12 109.44 2.19 3287200300010 14.7 2.00 0.14 107.43 1.99 3287200300011 ENDDATA 4 0 3287200300012 ENDSUBENT 11 0 3287200399999 SUBENT 32872004 20241211 32153287200400001 BIB 2 2 3287200400002 REACTION (29-CU-65(N,P)28-NI-65,,SIG) 3287200400003 DECAY-DATA (28-NI-65,2.5175HR,DG,1481.84,0.2359) 3287200400004 ENDBIB 2 0 3287200400005 NOCOMMON 0 0 3287200400006 DATA 5 2 3287200400007 EN DATA ERR-T MONIT MONIT-ERR 3287200400008 MEV MB MB MB MB 3287200400009 14.5 22.20 1.66 109.44 2.19 3287200400010 14.7 21.46 1.39 107.43 1.99 3287200400011 ENDDATA 4 0 3287200400012 ENDSUBENT 11 0 3287200499999 ENDENTRY 4 0 3287299999999
