half life of $^{133}$Bag ( t$_{1}$$_{/}$$_{2}$ = 10 . 52 yr). The partial cross section to the isomer $^{133}$Bam was measured via the 276 keV line (99.99% IT) to 〈 σ$_{exp}$ 〉 m = 35 . 5 ± 2 . 0 mbarn. The EC part of the isomeric decay is only 0.0096% and was, therefore, neglected. The total capture cross sec- tion of 〈 σ$_{exp}$ 〉 = 393 ± 15 mbarn was determined via the strongest transition in the EC decay to $^{133}$Cs at 356.0 keV (Table IX). 

c Including the respective uncertainty of gold (2.0-2.2%).

The (n, γ ) cross section of $^{156}$Dy was measured via the strongest line in the decay of $^{157}$Dy at 326 keV. The uncertainty of the measured value 〈 σ$_{exp}$ 〉 = 1641 ± 117 mbarn (Table X) is dominated by the contributions from the γ -ray intensity (3.2%) and from the isotopic abun- dance (5.4%).
