the estimated error in the measurement 1405600100041 of the neutron fluence, about 7%; 5% for the error in 1405600100042 the Ge detector efficiency; and the statistical 1405600100043 counting error 1405600100044 HISTORY (20051114C) DR 1405600100045 ENDBIB 43 0 1405600100046 NOCOMMON 0 0 1405600100047 ENDSUBENT 46 0 1405600199999 SUBENT 14056002 20051114 13391405600200001 BIB 3 3 1405600200002 REACTION (29-CU-0(N,X)25-MN-54,,SIG) 1405600200003 DECAY-DATA (25-MN-54,312.3D,DG,834.8,1.0) 1405600200004 STATUS Data taken from Table 2 1405600200005 ENDBIB 3 0 1405600200006 NOCOMMON 0 0 1405600200007 DATA 4 2 1405600200008 EN EN-RSL DATA ERR-T 1405600200009 MEV MEV MB MB 1405600200010 70.7 5.8 1.6 1.2 1405600200011 110.8 4.2 15.3 2.1 1405600200012 ENDDATA 4 0 1405600200013 ENDSUBENT 12 0 1405600299999 SUBENT 14056003 20051114 13391405600300001 BIB 3 3 1405600300002 REACTION (29-CU-0(N,X)27-CO-56,,SIG) 1405600300003 DECAY-DATA (27-CO-56,77.27D,DG,846.8,0.9995) 1405600300004 STATUS Data taken from Table 2 1405600300005 ENDBIB 3 0 1405600300006 NOCOMMON 0 0 1405600300007 DATA 4 2 1405600300008 EN EN-RSL DATA ERR-T 1405600300009 MEV MEV MB MB 1405600300010 70.7 5.8 3.4 0.6 1405600300011 110.8 4.2 6.3 0.9 1405600300012 ENDDATA 4 0 1405600300013 ENDSUBENT 12 0 1405600399999 SUBENT 14056004 20051114 13391405600400001 BIB 3 4 1405600400002 REACTION (29-CU-0(N,X)27-CO-57,,SIG) 1405600400003 DECAY-DATA (27-CO-57,271.79D,DG,122.1,0.856) 1405600400004 (27-CO-57,271.79D,DG,136.5,0.1068) 1405600400005 STATUS Data taken from Table 2 1405600400006 ENDBIB 4 0 1405600400007 NOCOMMON 0 0 1405600400008 DATA 4 2 1405600400009 EN EN-RSL DATA ERR-T 1405600400010 MEV MEV MB MB 1405600400011 70.7 5.8 15.1 2.7 1405600400012 110.8 4.2 39.7 5.1 1405600400013 ENDDATA 4 0 1405600400014 ENDSUBENT 13 0 1405600499999 SUBENT 14056005 20051114 13391405600500001 BIB 3 4 1405600500002 REACTION (29-CU-0(N,X)27-CO-58,,SIG) 1405600500003 DECAY-DATA (27-CO-58,70.82D,DG,810.8,0.9944) 1405600500004 (27-CO-58,70.82D,DG,863.96,0.0068) 1405600500005 STATUS Data taken from Table 2 1405600500006 ENDBIB 4 0 1405600500007 NOCOMMON 0 0 1405600500008 DATA 4 2 1405600500009 EN EN-RSL DATA ERR-T 1405600500010 MEV MEV MB MB 1405600500011 70.7 5.8 34.7 5.7 1405600500012 110.8 4.2 63.2 8.6 1405600500013 ENDDATA 4 0 1405600500014 ENDSUBENT 13 0 1405600599999 SUBENT 14056006 20051114 13391405600600001 BIB 3 3 1405600600002 REACTION (29-CU-0(N,X)26-FE-59,,SIG) 1405600600003 DECAY-DATA (26-FE-59,44.503D,DG,1099.3,0.565) 1405600600004 STATUS Data taken from Table 2 1405600600005 ENDBIB 3 0 1405600600006 NOCOMMON 0 0 1405600600007 DATA 4 2 1405600600008 EN EN-RSL DATA ERR-T 1405600600009 MEV MEV MB MB 1405600600010 70.7 5.8 3.0 1.2 1405600600011 110.8 4.2 4.2 1.2 1405600600012 ENDDATA 4 0 1405600600013 ENDSUBENT 12 0 1405600699999 SUBENT 14056007 20051114 13391405600700001 BIB 3 3 1405600700002 REACTION (29-CU-0(N,X)27-CO-60,,SIG) 1405600700003 DECAY-DATA (27-CO-60,5.271YR,DG,1332.5,1.0) 1405600700004 STATUS Data taken from Table 2 1405600700005 ENDBIB 3 0 1405600700006 NOCOMMON 0 0 1405600700007 DATA 4 2 1405600700008 EN EN-RSL DATA ERR-T 1405600700009 MEV MEV MB MB 1405600700010 70.7 5.8 17.6 8.6 1405600700011 110.8 4.2 29.1 8.6 1405600700012 ENDDATA 4 0 1405600700013 ENDSUBENT 12 0 1405600799999 ENDENTRY 7 0 1405699999999
