The solid tritium-titanium target used 3270500100019 in the neutron generator was about 2.18 mg/cm. 3270500100020 DETECTOR (HPGE) A calibrated GEM-60P coaxial HPGe detector were 3270500100021 used with 70.1x72.3 mm in diameter and length. And the 3270500100022 relative efficiency is around 68%, and the energy 3270500100023 resolution is around 1.7 keV (FWHM) at 1.33 MeV. 3270500100024 MONITOR (13-AL-27(N,A)11-NA-24,,SIG) 3270500100025 MONIT-REF (,M.Wagner+,B,PH-DAT,13-5,1990) 3270500100026 The cross section of monitor reaction was determined by3270500100027 interpolation of the evaluated values of the reference.3270500100028 ERR-ANALYS (ERR-T) Total uncertainty 3270500100029 (ERR-1) Detector efficiency at 5.5 cm (~2%) 3270500100030 CORRECTION Corrections were made for gamma-ray self-absorption in 3270500100031 the sample, for coincidence sum effect of cascade 3270500100032 gamma-rays, and for geometry correction factor. 3270500100033 STATUS (TABLE) Data taken from the Abstract in page 2295 of 3270500100034 J,ARI,70,2295,201206. 3270500100035 HISTORY (20120905C) Compiled by Youxiang ZHUANG (CNDC) 3270500100036 ENDBIB 34 0 3270500100037 COMMON 1 3 3270500100038 ERR-1 3270500100039 PER-CENT 3270500100040 2.0 3270500100041 ENDCOMMON 3 0 3270500100042 ENDSUBENT 41 0 3270500199999 SUBENT 32705002 20120905 31573270500200001 BIB 3 7 3270500200002 REACTION 1(90-TH-232(N,F)37-RB-89,,SIG) 3270500200003 2(90-TH-232(N,F)37-RB-89,,SIG) 3270500200004 3(90-TH-232(N,F)37-RB-89,,SIG) 3270500200005 DECAY-DATA1(37-RB-89,15.15MIN,DG,657.8,0.100) 3270500200006 2(37-RB-89,15.15MIN,DG,1031.9,0.580) 3270500200007 3(37-RB-89,15.15MIN,DG,1248.1,0.426) 3270500200008 STATUS (TABLE) Abstract of Appl.Radiat.Isotopes 70(2012)2295 3270500200009 ENDBIB 7 0 3270500200010 NOCOMMON 0 0 3270500200011 DATA 8 2 3270500200012 EN EN-RSL DATA 1ERR-T 1DATA 2ERR-T 23270500200013 DATA 3ERR-T 3 3270500200014 MEV MEV MB MB MB MB 3270500200015 MB MB 3270500200016 14.1 0.3 17.3 2.2 12.7 1.3 3270500200017 13.7 1.5 3270500200018 14.7 0.3 18.0 2.1 14.1 1.1 3270500200019 13.9 1.4 3270500200020 ENDDATA 8 0 3270500200021 ENDSUBENT 20 0 3270500299999 SUBENT 32705003 20120905 31573270500300001 BIB 3 5 3270500300002 REACTION (90-TH-232(N,F)37-RB-89,,SIG,,,DERIV) 3270500300003 ANALYSIS Simple average of cross sections for 1031.9 and 1248.1 3270500300004 keV gamma lines 3270500300005 STATUS (TABLE) Table 1 of Appl.Radiat.Isotopes 70(2012)2295 3270500300006 (DEP,32705002) Data from 1031.9 and 1248.1 keV gammas 3270500300007 ENDBIB 5 0 3270500300008 NOCOMMON 0 0 3270500300009 DATA 4 2 3270500300010 EN EN-RSL DATA ERR-T 3270500300011 MEV MEV MB MB 3270500300012 14.1 0.3 13.2 1.0 3270500300013 14.7 0.3 14.0 0.9 3270500300014 ENDDATA 4 0 3270500300015 ENDSUBENT 14 0 3270500399999 ENDENTRY 3 0 3270599999999
