These will be discussed in turn. 1124500300020 1) Correction due to background in the BF3 counters. 1124500300021 2) Correction due to displacement of D2O. 1124500300022 3) Correction due to the presence of oxygen and B11. 1124500300023 This correction is straightforward and simply corrects 1124500300024 the measured cross section for the presence of oxygen 1124500300025 and B11 to obtain the B10 total cross section. Total 1124500300026 cross sections of oxygen and B11 for this purpose were 1124500300027 taken from the literature; the magnitude of the 1124500300028 correction is less than 0.5%. 1124500300029 ERR-ANALYS (DATA-ERR) Total uncertainty 1124500300030 STATUS (TABLE) Authors data. 1124500300031 HISTORY (20210827A) BP: Added STATUS, SAMPLE, CORRECTION, 1124500300032 ANALYSIS, REL-REF. 1124500300033 ENDBIB 31 0 1124500300034 COMMON 1 3 1124500300035 EN-RSL 1124500300036 MICROSEC/M 1124500300037 2. 1124500300038 ENDCOMMON 3 0 1124500300039 DATA 3 82 1124500300040 EN DATA DATA-ERR 1124500300041 MEV B B 1124500300042 1.85E-08 4.48E+03 1124500300043 1.86E-08 4.46E+03 1124500300044 1.88E-08 4.45E+03 1124500300045 1.89E-08 4.55E+03 1124500300046 1.90E-08 4.48E+03 7.0E+02 1124500300047 1.92E-08 4.50E+03 1124500300048 1.93E-08 4.25E+03 1124500300049 1.95E-08 4.42E+03 1124500300050 1.97E-08 4.34E+03 1124500300051 1.99E-08 4.38E+03 1124500300052 2.00E-08 4.25E+03 1124500300053 2.02E-08 4.35E+03 1124500300054 2.03E-08 4.20E+03 1124500300055 2.04E-08 4.16E+03 1124500300056 2.07E-08 4.08E+03 1124500300057 2.09E-08 4.18E+03 1124500300058 2.10E-08 4.21E+03 1124500300059 2.12E-08 4.22E+03 1124500300060 2.13E-08 4.20E+03 1124500300061 2.15E-08 4.23E+03 1124500300062 2.16E-08 4.15E+03 1124500300063 2.18E-08 4.19E+03 1124500300064 2.19E-08 4.14E+03 1124500300065 2.22E-08 4.08E+03 1124500300066 2.24E-08 4.15E+03 1124500300067 2.27E-08 3.95E+03 1124500300068 2.28E-08 4.10E+03 1124500300069 2.30E-08 4.05E+03 1124500300070 2.33E-08 3.99E+03 1124500300071 2.34E-08 3.97E+03 1124500300072 2.37E-08 3.96E+03 1124500300073 2.39E-08 4.03E+03 1124500300074 2.40E-08 3.93E+03 1124500300075 2.46E-08 3.96E+03 1124500300076 2.48E-08 3.96E+03 1124500300077 2.51E-08 3.95E+03 1124500300078 2.53E-08 3.78E+03 1124500300079 2.55E-08 3.82E+03 1124500300080 2.58E-08 3.81E+03 1124500300081 2.59E-08 3.77E+03 1124500300082 2.62E-08 3.70E+03 1124500300083 2.65E-08 3.78E+03 1124500300084 2.67E-08 3.67E+03 1124500300085 2.69E-08 3.68E+03 1124500300086 2.72E-08 3.69E+03 1124500300087 2.74E-08 3.71E+03 1124500300088 2.77E-08 3.63E+03 1124500300089 2.79E-08 3.66E+03 1124500300090 2.82E-08 3.66E+03 1124500300091 2.86E-08 3.62E+03 1124500300092 2.87E-08 3.56E+03 5.0E+02 1124500300093 2.90E-08 3.64E+03 1124500300094 2.92E-08 3.51E+03 1124500300095 2.95E-08 3.54E+03 1124500300096 2.99E-08 3.57E+03 1124500300097 3.01E-08 3.49E+03 1124500300098 3.03E-08 3.50E+03 1124500300099 3.06E-08 3.51E+03 1124500300100 3.10E-08 3.54E+03 1124500300101 3.12E-08 3.42E+03 1124500300102 3.15E-08 3.46E+03 1124500300103 3.19E-08 3.54E+03 1124500300104 3.22E-08 3.42E+03 1124500300105 3.26E-08 3.33E+03 1124500300106 3.28E-08 3.39E+03 1124500300107 3.33E-08 3.41E+03 1124500300108 3.37E-08 3.30E+03 1124500300109 3.39E-08 3.32E+03 1124500300110 3.42E-08 3.24E+03 1124500300111 3.46E-08 3.24E+03 1124500300112 3.50E-08 3.29E+03 1124500300113 3.53E-08 3.27E+03 1124500300114 3.57E-08 3.23E+03 1124500300115 3.60E-08 3.19E+03 1124500300116 3.64E-08 3.19E+03 1124500300117 3.67E-08 3.12E+03 1124500300118 3.82E-08 3.13E+03 1124500300119 3.86E-08 3.11E+03 1124500300120 3.91E-08 3.10E+03 1124500300121 3.96E-08 3.04E+03 4.0E+02 1124500300122 4.01E-08 3.01E+03 1124500300123 4.04E-08 3.03E+03 1124500300124 ENDDATA 84 0 1124500300125 ENDSUBENT 124 0 1124500399999 SUBENT 11245004 20210827 14911124500400001 BIB 6 9 1124500400002 REACTION (5-B-10(N,TOT),,SIG,,,DERIV) 1124500400003 ASSUMED (ASSUM,5-B-10(N,SCT)5-B-10,,SIG) 1124500400004 ANALYSIS Fitting to the total cross section between 0.018 and 1124500400005 0.4 eV assuming 1/v shape 1124500400006 ERR-ANALYS (DATA-ERR) No details on sources of uncertainties. 1124500400007 STATUS (DEP,11245003) 1124500400008 (TABLE) page 114. 1124500400009 HISTORY (20210827A) BP: Added STATUS, ERR-ANALYS, corrected 1124500400010 reaction. 1124500400011 ENDBIB 9 0 1124500400012 COMMON 1 3 1124500400013 ASSUM 1124500400014 B 1124500400015 4.0 1124500400016 ENDCOMMON 3 0 1124500400017 DATA 3 1 1124500400018 EN DATA DATA-ERR 1124500400019 EV B B 1124500400020 0.0253 3848. 38. 1124500400021 ENDDATA 3 0 1124500400022 ENDSUBENT 21 0 1124500499999 NOSUBENT 11245005 20210827 14911124500500001 ENDENTRY 5 0 1124599999999
