The Cd(In) ratio was about 1413300100014 2 x 1E3. 1413300100015 SAMPLE The Pd sample weighed 201.4 +/- 0.1 mg and its isotopic1413300100016 composition is 1413300100017 Atomic percent 1413300100018 104 1.61 +/- 0.02 1413300100019 105 48.50 +/- 0.05 1413300100020 106 22.90 +/- 0.05 1413300100021 107 15.54 +/- 0.05 1413300100022 108 8.77 +/- 0.02 1413300100023 110 2.68 +/- 0.02 1413300100024 The largest chemical contaminant was 0.1% iron 1413300100025 DETECTOR (GE) The gamma rays emitted in the (nth,g) reaction 1413300100026 were measured with a 26-cm3 coaxial Ge(Li) detector 1413300100027 positioned inside a 20 cm-outer diameter x 30 cm-long 1413300100028 NaI(Tl) annulus. 1413300100029 METHOD (ACTIV) 1413300100030 MONITOR A 100.0 +/- 0.1 mg sample of (CH2)n was placed at the 1413300100031 target position together with the Zr sample in the 1413300100032 thermal column.
