Due to small fission 3270000100011 cross sections, the effects of 238-Pu and 240-Pu in 3270000100012 sample is small. 3270000100013 METHOD (RELFY,GSPEC) Relative measurements of fission 3270000100014 products 88Rb, 95Y, 101Mo, 101Tc 138Cs and 142La at 3270000100015 thermal neutron induced. 3270000100016 DETECTOR (HPGE) 3270000100017 1) The volume of HPGe detector is 110 cm3. 3270000100018 2) The relative efficiency is around 40%. 3270000100019 MONITOR (94-PU-239(N,F)40-ZR-97,CUM,FY) 3270000100020 ANALYSIS Decay gamma spectrum area was determined with SPAN 3270000100021 code, and fission yield was calculated by FYAUTOLS 3270000100022 code. 3270000100023 CORRECTION To subtract the contamination from interfere nuclides, 3270000100024 the half-life analysis method was adopted. 3270000100025 ERR-ANALYS (ERR-T) Total uncertainty of measurement mainly due to 3270000100026 monitor data, gamma counting statistics. Uncertainty 3270000100027 due to decay data is excluded. 3270000100028 (MONIT-ERR) Uncertainty of the reference nuclei 3270000100029 fission yield of 97Zr. 3270000100030 (ERR-1,,2.0) Uncertainty of efficiency of HPGe is less 3270000100031 than 2.0%. 3270000100032 DECAY-DATA (37-RB-88,17.78MIN,DG,1836.0,0.214) 3270000100033 (39-Y-95,10.3MIN,DG,954.0,0.158) 3270000100034 (42-MO-101,14.84MIN,DG,2032.1,0.0694) 3270000100035 (43-TC-101,14.22MIN,DG,306.8,0.880) 3270000100036 (55-CS-138-G,32.17MIN,DG,1435.9,0.763) 3270000100037 (57-LA-142,90.85MIN,DG,641.3,0.474) 3270000100038 STATUS (TABLE) Data were taken from Table 3 at page 91 in 3270000100039 J,HFH,34,(2),88,2012. 3270000100040 HISTORY (20120816C) Compiled by Guochang CHEN (CNDC) 3270000100041 ENDBIB 39 0 3270000100042 COMMON 3 3 3270000100043 EN-DUMMY MONIT MONIT-ERR 3270000100044 EV PC/FIS PC/FIS 3270000100045 0.0253 5.304 0.069 3270000100046 ENDCOMMON 3 0 3270000100047 ENDSUBENT 46 0 3270000199999 SUBENT 32700002 20120816 31573270000200001 BIB 1 1 3270000200002 REACTION (94-PU-239(N,F)ELEM/MASS,CUM,FY) 3270000200003 ENDBIB 1 0 3270000200004 NOCOMMON 0 0 3270000200005 DATA 5 6 3270000200006 ELEMENT MASS ISOMER DATA ERR-T 3270000200007 NO-DIM NO-DIM NO-DIM PC/FIS PC/FIS 3270000200008 37. 88. 1.32 0.05 3270000200009 39. 95. 4.69 0.22 3270000200010 42. 101. 6.13 0.32 3270000200011 43. 101. 6.10 0.22 3270000200012 55. 138. 0. 6.24 0.24 3270000200013 57. 142. 4.74 0.17 3270000200014 ENDDATA 8 0 3270000200015 ENDSUBENT 14 0 3270000299999 ENDENTRY 2 0 3270099999999
