The fast flux in the irradiation box 3033900100010 was about 10**13 neutrons/(cm2*sec). 3033900100011 INC-SPECT Using four standard reactions of different threshold 3033900100012 energies no departures from a fission spectrum were 3033900100013 found. No additional information given. 3033900100014 Compiler's comment: Note that, although the threshold 3033900100015 energy of the reaction concerned is above 7 MeV, a 3033900100016 'dummy-energy' for the fission neutron spectrum of 3033900100017 2 MeV had to be entered. 3033900100018 METHOD (ACTIV) Activation method 3033900100019 DETECTOR (GELI) Germanium-lithium detector. The efficiency 3033900100020 curve was obtained using standardized sources followed 3033900100021 by least square fitting, the absolute efficiency by 3033900100022 comparison with a Cs-137 source. 3033900100023 MONITOR Four different standard reactions were used. For the 3033900100024 results obtained with the different standards see 3033900100025 subentries 002-005. 3033900100026 The values of the standard cross-sections were taken 3033900100027 from A.Calamand, Handbook on Nuclear Activation Cross- 3033900100028 sections, pg.273, Technical report series no.156, 3033900100029 IAEA, Vienna (1974). 3033900100030 PART-DET (DG) Decay gammas 3033900100031 DECAY-DATA (81-TL-202-G,12.23D) 3033900100032 COMMENT Authors calculated a mean value of the measurements 3033900100033 with 4 different standards = 4.0 +- 0.32 mb. 3033900100034 STATUS (TABLE) Data taken from J.Inorg.Nucl.Chem.38(1976)1386.3033900100035 HISTORY (19760831C) OS. 3033900100036 (20090125A) BIB section updated 3033900100037 ERR-ANALYS No errors of the individual measurements are given. 3033900100038 The error of the mean value includes: 3033900100039 (ERR-1) errors of efficiency determination and due to 3033900100040 the dispersion of the obtained cross-section values 3033900100041 (1.8%) 3033900100042 (ERR-2) error of standard cross sections (6.2%). 3033900100043 No information on statistical errors given. 3033900100044 ENDBIB 42 0 3033900100045 COMMON 3 3 3033900100046 EN-DUMMY ERR-1 ERR-2 3033900100047 MEV PER-CENT PER-CENT 3033900100048 2.0000E+00 1.8 6.2 3033900100049 ENDCOMMON 3 0 3033900100050 ENDSUBENT 49 0 3033900199999 SUBENT 30339002 20090115 31343033900200001 BIB 3 4 3033900200002 REACTION (81-TL-203(N,2N)81-TL-202,,SIG,,FIS) 3033900200003 ANALYSIS Average of two measurements (3.98 and 3.95 mb, 3033900200004 respectively). 3033900200005 MONITOR (26-FE-54(N,P)25-MN-54,,SIG,,FIS) 3033900200006 ENDBIB 4 0 3033900200007 NOCOMMON 0 0 3033900200008 DATA 3 1 3033900200009 DATA MONIT MONIT-ERR 3033900200010 MB MB MB 3033900200011 3.9650E+00 8.2500E+01 5.0000E+00 3033900200012 ENDDATA 3 0 3033900200013 ENDSUBENT 12 0 3033900299999 SUBENT 30339003 20090115 31343033900300001 BIB 3 4 3033900300002 REACTION (81-TL-203(N,2N)81-TL-202,,SIG,,FIS) 3033900300003 ANALYSIS Average of two measurements (4.00 and 4.01 mb, 3033900300004 respectively). 3033900300005 MONITOR (28-NI-58(N,P)27-CO-58,,SIG,,FIS) 3033900300006 ENDBIB 4 0 3033900300007 NOCOMMON 0 0 3033900300008 DATA 3 1 3033900300009 DATA MONIT MONIT-ERR 3033900300010 MB MB MB 3033900300011 4.0050E+00 1.1300E+02 7.0000E+00 3033900300012 ENDDATA 3 0 3033900300013 ENDSUBENT 12 0 3033900399999 SUBENT 30339004 20090115 31343033900400001 BIB 2 2 3033900400002 REACTION (81-TL-203(N,2N)81-TL-202,,SIG,,FIS) 3033900400003 MONITOR (12-MG-24(N,P)11-NA-24,,SIG,,FIS) 3033900400004 ENDBIB 2 0 3033900400005 NOCOMMON 0 0 3033900400006 DATA 3 1 3033900400007 DATA MONIT MONIT-ERR 3033900400008 MB MB MB 3033900400009 4.0600E+00 1.5300E+00 9.0000E-02 3033900400010 ENDDATA 3 0 3033900400011 ENDSUBENT 10 0 3033900499999 SUBENT 30339005 20090115 31343033900500001 BIB 2 2 3033900500002 REACTION (81-TL-203(N,2N)81-TL-202,,SIG,,FIS) 3033900500003 MONITOR (13-AL-27(N,A)11-NA-24,,SIG,,FIS) 3033900500004 ENDBIB 2 0 3033900500005 NOCOMMON 0 0 3033900500006 DATA 3 1 3033900500007 DATA MONIT MONIT-ERR 3033900500008 MB MB MB 3033900500009 4.0100E+00 7.2500E-01 4.5000E-02 3033900500010 ENDDATA 3 0 3033900500011 ENDSUBENT 10 0 3033900599999 ENDENTRY 5 0 3033999999999
