Times Cited Count:1 Percentile:10.40(Nuclear Science & Technology)The present study performed integral experiments of I using a fast-neutron source reactor "YAYOI" of the University of Tokyo to validate evaluated nuclear data libraries. The iodine-129 sample and flux monitors were irradiated by fast neutrons in the Glory hole of the YAYOI reactor. Reaction rates of
I were obtained by measurement of decay gamma-rays emitted from
I. The validity of the fast-neutron flux spectrum in the Glory hole was confirmed by the
ratios of the reaction rates of flux monitors. The experimental reaction rate of
I was compared with that calculated with both the fast-neutron flux spectrum and evaluated nuclear data libraries. The present study revealed that the evaluated nuclear data of
I cited in JENDL-4.0 should be reduced as much as 18% in neutron energies ranging from 10 keV to 3 MeV, and supported the reported data by Noguere
below 100 keV.

Technetium-99 samples were irradiated with reactor neutrons using a pneumatic system. Reaction rates of
Tc were obtained by measuring decay gamma rays emitted from
Tc. The neutron flux at an irradiation position was monitored with gold foils. The fast-neutron capture cross section of
Tc at neutron energy of 85 keV was derived as 0.432
0.023 barn by using the reaction rates of
Tc, evaluated cross-section data and the fast-neutron flux spectrum of the YAYOI reactor. The present study agreed with the evaluated nuclear data library JENDL-4.0.

Times Cited Count:0 Percentile:0.00(Chemistry, Multidisciplinary)For accuracy improvement of neutron activation analysis and neutron capture cross section, bias effects are investigated on g- and s-factors in the Westcott convention. As origins of biases, a joining function shape, neutron temperature and sample temperature, have been investigated. Biases are quantitatively deduced for two 1/v isotopes (Au,
Co) and six non-1/v isotopes (
Am,
Eu,
Rh,
In,
Hf,
Ra). The s-factor calculated with a joining function deduced recently by a detailed Monte Carlo simulation is compared to s-factors calculated with traditional joining functions by Westcott. The results show the bias induced by sample temperature is small as the order of 0.1% for g-factor and the order of 1% for s-factor. On the other hand, biases induced by a joining function shape for s-factor depend significantly on both isotopes and neutron temperature. As the result, reaction rates are also affected significantly as well. The bias size on reaction rate is given in the case of epithermal neutron index r = 0.1, for the eight isotopes.

This paper explained the activities of the International Nuclear Data Evaluation Co-operation (WPEC)'s subgroup SG-41, which was carried out to improve the accuracy of nuclear data. In this paper, by focusing on how to deal with discrepant data, the method of deriving recommended values from multiple measurement results was reviewed. It also explained how to derive the recommended values, including exercises.
