The distance 3275600100011 between target and sample is 5~28 cm. The V sample in 3275600100012 each group was sandwiched between two Al foils. 3275600100013 INC-SOURCE (D-T) An effective deuteron beam energy and beam 3275600100014 current is 125 keV and about 20 mA. T-Ti target was 3275600100015 around 0.9 mg/cm2 thick. Neutron yield is 2E12 n/s. 3275600100016 DETECTOR (HPGE) A CH8403 coaxial high-purity germanium 3275600100017 detector with a relative efficiency of 20% and an 3275600100018 energy resolution of 2.6 keV at 1.33 MeV. The 3275600100019 efficiency was calibrated by a standard gamma-source, 3275600100020 standard reference material 4275 from the National 3275600100021 Institute of Standards and Technology. In gamma ray 3275600100022 measurement, the distance between sample and HPGe is 3275600100023 2 cm. 3275600100024 (FISCH) The neutron flux was monitored by a uranium 3275600100025 fission chamber. 3275600100026 METHOD (ACTIV) The irradiation was lasted 0.5 and 6 hours, 3275600100027 the angle is from 0 to 130 degree between deuteron 3275600100028 beam and target. 3275600100029 MONITOR (13-AL-27(N,A)11-NA-24,,SIG) 3275600100030 MONIT-REF (,H.Vonach,R,STI/DOC/10-227,59,1983) 3275600100031 DECAY-MON (11-NA-24,14.659HR,DG,1368.598,1.0) 3275600100032 ERR-ANALYS (ERR-T) The total uncertainty. 3275600100033 (ERR-1) The absolute efficiency curve of HPGe at 2 cm 3275600100034 from neutron source 1.5%. 3275600100035 (ERR-2) The detector efficiency for 24Na 1.5%. 3275600100036 (ERR-3) Gamma self-absorption correction 1.0%. 3275600100037 (ERR-4) Gamma self-absorption correction for 24Na 1.0%.3275600100038 (ERR-5) Distance between sample and detector 1.0%. 3275600100039 (ERR-6) Distance between sample and detector for 24Na 3275600100040 1.0%. 3275600100041 (ERR-7) Sample weight for 51V 0.1%. 3275600100042 (ERR-8) Sample weight for 27Al 0.2%. 3275600100043 (ERR-9,0.8,1.1,U) Statistical uncertainty for 24Na 3275600100044 0.8~1.1%. 3275600100045 (ERR-10) Uncertainty due to neutron energy uncertainty 3275600100046 0.4%. 3275600100047 (MONIT-ERR,1.2,1.5) Monitor cross sections 1.2~1.5%. 3275600100048 STATUS (TABLE) Data were obtained from TABLE 2 of J.Lanzhou 3275600100049 University (Natural Sciences),35,79,1999. 3275600100050 HISTORY (20180521C) Compiled by Guochang Chen (CNDC) 3275600100051 ENDBIB 49 0 3275600100052 COMMON 9 6 3275600100053 ERR-1 ERR-2 ERR-3 ERR-4 ERR-5 ERR-6 3275600100054 ERR-7 ERR-8 ERR-10 3275600100055 PER-CENT PER-CENT PER-CENT PER-CENT PER-CENT PER-CENT 3275600100056 PER-CENT PER-CENT MEV 3275600100057 1.5 1.5 1.0 1.0 1.0 1.03275600100058 0.1 0.2 0.4 3275600100059 ENDCOMMON 6 0 3275600100060 ENDSUBENT 59 0 3275600199999 SUBENT 32756002 20180521 31853275600200001 BIB 3 3 3275600200002 REACTION (23-V-51(N,A)21-SC-48,,SIG) 3275600200003 DECAY-DATA (21-SC-48,1.821D,DG,1312.046,1.0) 3275600200004 ERR-ANALYS (ERR-S,1.8,3.5,U) statistical uncertainty. 3275600200005 ENDBIB 3 0 3275600200006 NOCOMMON 0 0 3275600200007 DATA 4 6 3275600200008 EN EN-ERR DATA ERR-T 3275600200009 MEV MEV MB MB 3275600200010 13.5 0.2 14.27 0.42 3275600200011 13.7 0.2 14.39 0.49 3275600200012 14.2 0.2 14.88 0.47 3275600200013 14.4 0.2 15.24 0.53 3275600200014 14.6 0.2 16.89 0.64 3275600200015 14.8 0.2 17.04 0.75 3275600200016 ENDDATA 8 0 3275600200017 ENDSUBENT 16 0 3275600299999 SUBENT 32756003 20180521 31853275600300001 BIB 3 3 3275600300002 REACTION (23-V-51(N,P)22-TI-51,,SIG) 3275600300003 DECAY-DATA (22-TI-51,5.760MIN,DG,320.084,0.930) 3275600300004 ERR-ANALYS (ERR-S,2.5,3.8,U) statistical uncertainty. 3275600300005 ENDBIB 3 0 3275600300006 NOCOMMON 0 0 3275600300007 DATA 4 6 3275600300008 EN EN-ERR DATA ERR-T 3275600300009 MEV MEV MB MB 3275600300010 13.5 0.2 30.7 1.2 3275600300011 13.7 0.2 29.2 1.2 3275600300012 14.2 0.2 27.8 1.1 3275600300013 14.4 0.2 27.1 1.1 3275600300014 14.6 0.2 26.7 1.1 3275600300015 14.8 0.2 26.2 1.1 3275600300016 ENDDATA 8 0 3275600300017 ENDSUBENT 16 0 3275600399999 ENDENTRY 3 0 3275699999999
