1275300500005 STATUS (TABLE) Table 1, page 811 (J,AJ,313,808,1987). 1275300500006 HISTORY (20120210C) BP 1275300500007 ERR-ANALYS (DATA-ERR) Quoted uncertainties are primarily due to 1275300500008 the uncertainty associated with the neutron and 1275300500009 gamma-ray strength functions used in the extrapolation 1275300500010 below the lower energy limits of the measurements, 1275300500011 but include also uncertainties due to counting 1275300500012 statistics and background subtractions. 1275300500013 (ERR-SYS) A 4% error due to conversion of measured 1275300500014 capture yields to cross section should be added in 1275300500015 quadrature to the quoted uncertainty. 1275300500016 COMMENT The present (reanalyzed) data reduction relies on the 1275300500017 reproducibility of the neutron flux monitor and the 1275300500018 near constancy of the ORELA flux shape. 1275300500019 ENDBIB 17 0 1275300500020 COMMON 1 3 1275300500021 ERR-SYS 1275300500022 PER-CENT 1275300500023 4.0
