The neutron 3275400100014 energies at 0, 40, 60, 96, 110 and 130 degree were 3275400100015 measured by silicon detector method. 3275400100016 DETECTOR (HPGE) A CH8403 coaxial high-purity germanium 3275400100017 detector with a relative efficiency of 20% and an 3275400100018 energy resolution of 2.6 keV at 1.332 keV. The 3275400100019 distance between sample and detector is 2 cm. 3275400100020 (SI) Neutron energy was determined by silicon detector.3275400100021 METHOD (ACTIV) The irradiation was lasted 6 hours, the angle 3275400100022 is 0, 40, 60, 96, 110 and 130 degree between deuteron 3275400100023 beam and target. 3275400100024 MONITOR (41-NB-93(N,2N)41-NB-92-M,,SIG) 3275400100025 MONIT-REF (,Lu Hanlin+,J,CNP,6,76,1984) 3275400100026 DECAY-MON (41-NB-92-M,10.16D,DG,934.5,0.990) 3275400100027 ERR-ANALYS (ERR-T) The total uncertainty. 3275400100028 (ERR-1) The detector efficiency 1.0%. 3275400100029 (ERR-2) Gamma self-absorption 0.5%. 3275400100030 (ERR-3) Detection geometry correction 0.5%. 3275400100031 (ERR-4) Uncertainty of neutron flux fluctuation 0.5%. 3275400100032 (ERR-S) Statistical uncertainty 1.0%. 3275400100033 (MONIT-ERR) Uncertainty of monitor cross sections 1.5%.3275400100034 STATUS (TABLE) Data were obtained from TABLE at page 58 of 3275400100035 J.Lanzhou University (Natural Sciences),32,57,1996. 3275400100036 HISTORY (20170820C) Compiled by Guochang Chen (CNDC). 3275400100037 ENDBIB 35 0 3275400100038 COMMON 5 3 3275400100039 ERR-1 ERR-2 ERR-3 ERR-4 ERR-S 3275400100040 PER-CENT PER-CENT PER-CENT PER-CENT PER-CENT 3275400100041 1.0 0.5 0.5 0.5 1.0 3275400100042 ENDCOMMON 3 0 3275400100043 ENDSUBENT 42 0 3275400199999 SUBENT 32754002 20170820 31813275400200001 BIB 3 3 3275400200002 REACTION (40-ZR-90(N,2N)40-ZR-89,,SIG) 3275400200003 SAMPLE (40-ZR-90,NAT=0.515) 3275400200004 DECAY-DATA (40-ZR-89-G,3.268D,DG,909.1,0.999) 3275400200005 ENDBIB 3 0 3275400200006 COMMON 1 3 3275400200007 EN-ERR 3275400200008 MEV 3275400200009 0.02 3275400200010 ENDCOMMON 3 0 3275400200011 DATA 5 6 3275400200012 EN DATA ERR-T MONIT MONIT-ERR 3275400200013 MEV MB MB MB MB 3275400200014 13.64 483.0 10.6 451.4 7.4 3275400200015 13.80 539.7 11.9 453.5 6.0 3275400200016 14.01 606.3 13.3 455.9 5.0 3275400200017 14.35 710.6 15.6 458.4 4.5 3275400200018 14.62 775.4 17.1 458.8 5.0 3275400200019 14.80 825.5 18.2 458.6 5.6 3275400200020 ENDDATA 8 0 3275400200021 ENDSUBENT 20 0 3275400299999 ENDENTRY 2 0 3275499999999
