Activation Cross Sections

The ratio of resonance integral to thermal activation cross sections of the isotopes 64Zn, 68Zn, 85Rb, 100Mo, 102Ru, 113In, 123Sb, and 180Hf relative to gold has been determined by measuring cadmium ratios.The standard gold or a secondary standard was mixed uniformly in the samples and the activities resolved with a lithium-drift germanium γ-ray spectrometer. Expressed as Westcott S0 values the results were: 64Zn = 2.06 ± 0.03, 68Zn = 3.72 ± 0.14, 85Rb = 18.4 ± 0.6, 100Mo = 21.7 ± 0.8, 102Ru = 3.76 ± 0.03, 113In = 24.7 ± 0.5, 123Sb = 28.3 ± 2.1, 180Hf = 2.17 ± 0.09. All measurements are relative to S0 = 17.7 for gold.

A lithium-drift germanium γ-ray spectrometer has been used to make accurate intercomparisons of the ratio of resonance-integral to thermal-activation cross section by measuring cadmium ratios or relative activation rates in two different neutron spectra. The standard, gold, or secondary standard, indium, was mixed uniformly in the samples and the activities resolved with the spectrometer. Expressed as Westcott s0 values, the results relative to s0 = 17.7 for gold were as follows: 74Se = 10.3 ± 0.1, 78Se = 12.3 ± 0.3, 80Se = 2.65 ± 0.02, 81Br = 24.3 ± 0.5, 127I = 27.8 ± 0.5, 130Te = 2.10 ± 0.07, 138Ba = 0.649 ± 0.004, 140Ce = 0.476 ± 0.003, 142Ce = 0.865 ± 0.005.
