The Nb sample in each group 3275700100010 was sandwiched between two Zr foils. 3275700100011 INC-SOURCE (D-T) Neutron yield is around 3E12 n/s. T-Ti taret 3275700100012 was around 0.9 mg/cm2 thick. The neutron energies at 3275700100013 0, 50, 90 and 120 degree were determined by cross 3275700100014 section ratios of 90-Zr(n,2n)89m+g-Zr and 3275700100015 93-Nb(n,2n)92m-Nb. 3275700100016 DETECTOR (HPGE) A CH8403 coaxial high-purity germanium 3275700100017 detector with a relative efficiency of 20% and an 3275700100018 energy resolution of 3 keV at 1.33 MeV. In gamma ray 3275700100019 measurement, the distance between sample and HPGe is 3275700100020 2 cm. 3275700100021 (FISCH) The neutron flux was monitored by a uranium 3275700100022 fission chamber. 3275700100023 METHOD (ACTIV) The irradiation was lasted 568 hours, the 3275700100024 angle is 0, 50, 90 and 120 degree between deuteron 3275700100025 beam and target. Counting was finished after 2-8 hrs 3275700100026 after irradiation. 3275700100027 MONITOR (41-NB-93(N,2N)41-NB-92-M,,SIG) 3275700100028 MONIT-REF (,W.R.Zhao+,R,INDC(CPR)-16,55,1989) 3275700100029 DECAY-MON (41-NB-92-M,10.15D,DG,934.53,0.992) 3275700100030 ERR-ANALYS (ERR-T) The total uncertainty. 3275700100031 (ERR-1) Uncertainty of neutron energy 0.4%. 3275700100032 (ERR-2) The detector efficiency for 95Zr 1.5%. 3275700100033 (ERR-3) The detector efficiency for 92mNb 1.5%. 3275700100034 (ERR-4) Gamma self-absorption for 95Zr 1.0%. 3275700100035 (ERR-5) Gamma self-absorption for 92mNb 1.0%. 3275700100036 (ERR-6) The distance between sample and detector for 3275700100037 95Zr 1.0%. 3275700100038 (ERR-7) The distance between sample and detector for 3275700100039 92mNb 1.0%. 3275700100040 (ERR-8) Sample weight for 96Zr 0.1%. 3275700100041 (ERR-9) Sample weight for 93Nb 0.15%. 3275700100042 (ERR-10,1.1,2.5,U) Statistical uncertainty for 95Zr 3275700100043 1.1~2.5%. 3275700100044 (ERR-11,0.6,1.1,U) Statistical uncertainty for 92mNb 3275700100045 0.6-1.1%. 3275700100046 (MONIT-ERR) monitor cross sections 1.2~1.5%. 3275700100047 STATUS (TABLE) Data were obtained from TABLE2 of J.Lanzhou 3275700100048 University (Natural Sciences),39,107,2003. 3275700100049 HISTORY (20170824C) Compiled by Guochang Chen (CNDC). 3275700100050 ENDBIB 48 0 3275700100051 COMMON 9 6 3275700100052 ERR-1 ERR-2 ERR-3 ERR-4 ERR-5 ERR-6 3275700100053 ERR-7 ERR-8 ERR-9 3275700100054 PER-CENT PER-CENT PER-CENT PER-CENT PER-CENT PER-CENT 3275700100055 PER-CENT PER-CENT PER-CENT 3275700100056 0.4 1.5 1.5 1.0 1.0 1.03275700100057 1.0 0.1 0.15 3275700100058 ENDCOMMON 6 0 3275700100059 ENDSUBENT 58 0 3275700199999 SUBENT 32757002 20170824 31813275700200001 BIB 2 2 3275700200002 REACTION (40-ZR-96(N,2N)40-ZR-95,,SIG) 3275700200003 DECAY-DATA (40-ZR-95,64.02D,DG,756.729,0.5446) 3275700200004 ENDBIB 2 0 3275700200005 NOCOMMON 0 0 3275700200006 DATA 5 4 3275700200007 EN DATA ERR-T MONIT MONIT-ERR 3275700200008 MEV MB MB MB MB 3275700200009 13.6 1558. 63. 450.7 7.4 3275700200010 14.2 1459. 62. 457.6 4.5 3275700200011 14.4 1465. 66. 458.7 4.5 3275700200012 14.7 1555. 71. 458.6 5.6 3275700200013 ENDDATA 6 0 3275700200014 ENDSUBENT 13 0 3275700299999 ENDENTRY 2 0 3275799999999
