The resolution of the 120 cm3 HPGe 32793 1 17 detector was 1.85 keV (FWHM) for the 1.33 MeV gamma 32793 1 18 ray of Co-60. 32793 1 19 (FISCH) The sample sandwiched between two 32793 1 20 standardized thin samples was mounted in a double 32793 1 21 fission chamber, which covered with Cd of 1 mm 32793 1 22 thickness. The efficiency of the fission chamber was 32793 1 23 checked by 197Au(n,g) 198Au reaction with thermal 32793 1 24 neutrons. 32793 1 25 METHOD (TOF) Time of flight technique was used to measure 32793 1 26 the neutron spectrum. 32793 1 27 (GSPEC) Fission product activities were measured by 32793 1 28 HPGe gamma-ray spectrometry. Four samples were 32793 1 29 irradiated for a period varying from 0.5 to 30 h at a 32793 1 30 distance of about 5 cm from the neutron source in the 32793 1 31 direction of zero degree. 32793 1 32 (ABSFY) Fission rate was monitored by fission chamber. 32793 1 33 DECAY-DATA (35-BR-84-G,31.8MIN,DG,881.2,0.42) 32793 1 34 (36-KR-85-M,268.8MIN,DG,304.9,0.140) 32793 1 35 (36-KR-87,76.3MIN,DG,402.6,0.496) 32793 1 36 (36-KR-88,170.4MIN,DG,196.3,0.2558) 32793 1 37 (37-RB-89,15.15MIN,DG,1248.1,0.4257) 32793 1 38 (38-SR-91,577.8MIN,DG,555.6,0.615) 32793 1 39 (38-SR-92,162.6MIN,DG,1384.1,0.90) 32793 1 40 (39-Y-93-G,610.8MIN,DG,266.9,0.073) 32793 1 41 (39-Y-94,18.7MIN,DG,918.8,0.56) 32793 1 42 (40-ZR-95,92189.MIN,DG,756.7,0.5446) 32793 1 43 (40-ZR-97,1014.MIN,DG,742.7,0.9306) 32793 1 44 (42-MO-99,3956.7MIN,DG,739.5,0.1214) 32793 1 45 (43-TC-101,14.2MIN,DG,306.5,0.88) 32793 1 46 (44-RU-103,56526.MIN,DG,497.1,0.909) 32793 1 47 (43-TC-104,18.3MIN,DG,358.,0.89) 32793 1 48 (44-RU-105,266.4MIN,DG,724.2,0.473) 32793 1 49 (47-AG-112,187.8MIN,DG,617.5,0.435) 32793 1 50 (48-CD-115-G,3208.3MIN,DG,336.3,0.501) 32793 1 51 (51-SB-127,5544.MIN,DG,473.2,0.256) 32793 1 52 (50-SN-128-G,59.1MIN,DG,482.,0.59) 32793 1 53 (53-I-131,11577.6MIN,DG,637.,0.0717) 32793 1 54 (52-TE-132,4694.4MIN,DG,228.3,0.882) 32793 1 55 (53-I-133-G,1248.MIN,DG,529.8,0.87) 32793 1 56 (53-I-134-G,52.6MIN,DG,847.1,0.954) 32793 1 57 (53-I-135,394.2MIN,DG,1131.5,0.2274) 32793 1 58 (55-CS-138-G,33.41MIN,DG,1435.8,0.763) 32793 1 59 (56-BA-140,18354.MIN,DG,537.3,0.2439) 32793 1 60 (56-BA-141,18.27MIN,DG,190.3,0.46) 32793 1 61 (57-LA-142,91.1MIN,DG,641.3,0.474) 32793 1 62 (58-CE-143,1980.MIN,DG,293.3,0.428) 32793 1 63 (59-PR-146,24.15MIN,DG,453.9,0.48) 32793 1 64 (60-ND-147,15811.2MIN,DG,531.,0.131) 32793 1 65 CORRECTION Corrections were made for the gamma self-absorption, 32793 1 66 gamma geometry, gamma cascade coincidence losses and 32793 1 67 fission induced by background neutrons. 32793 1 68 ERR-ANALYS (DATA-ERR) Uncertainties (1 sigma) of the yields were 32793 1 69 obtained by consideration of all known sources of 32793 1 70 systematic and random errors such as mass 32793 1 71 determination of standard sample, detector efficiency 32793 1 72 of HPGe spectra system, statistic error of gamma-ray 32793 1 73 peak area, and corrections, with the usual rules of 32793 1 74 error propagation.
