The lengths were chosen3017300100015 so that the transmissions were about 50% 3017300100016 METHOD (TRN) Transmission measurements in good geometry 3017300100017 DETECTOR (SCIN) The detector was a 2*2 cm stilbene scintillator.3017300100018 The monitor was a 2.2*3 cm anthracene crystal. 3017300100019 Both are mounted on rca 6810a photomultipliers. Pulse- 3017300100020 shape discrimination was used against gamma-ray 3017300100021 background. The bias-window method was used to 3017300100022 eliminate electronic instability. 3017300100023 Tritium target-detector distance = 60 cm, the sample 3017300100024 was placed midway between them. 3017300100025 PART-DET (N) neutrons. 3017300100026 COMMENT The measured data are averaged over 4 or 5 independent 3017300100027 measurements. 3017300100028 ERR-ANALYS (ERR-S) The statistical errors in the transmission 3017300100029 data are less than 0.5%. After background and 3017300100030 in-scattering corrections they amount to 1% 3017300100031 (ERR-SYS) Systematic errors (e.g. in the weight and 3017300100032 diameter of sample) are identical at all energies and 3017300100033 also amount to about 1% 3017300100034 Statistical and systematic errors on carbone and teflon3017300100035 total cross-sections are combined to obtain the 2% 3017300100036 errors on fluor total cross-section 3017300100037 STATUS (TABLE) Data from Angeli'S letter of 6 July 1972. 3017300100038 (APRVD) Approved by Angeli (19721024) 3017300100039 HISTORY (19720721C) CA. 3017300100040 (20080208A) BIB section updated 3017300100041 CORRECTION Background and in-scattering corrections were taken 3017300100042 into account. 3017300100043 .The background was measured to be 0.9% and 3017300100044 1.6% at 14.60 and 13.70 MeV respectively. 3017300100045 .The magnitude of the in-scattering correction was 3017300100046 1.2% of the measured cross section for Be and 3017300100047 0.7% for C and F. 3017300100048 ENDBIB 46 0 3017300100049 NOCOMMON 0 0 3017300100050 ENDSUBENT 49 0 3017300199999 SUBENT 30173002 20080208 31263017300200001 BIB 2 2 3017300200002
