Nuclear data and measurements for the¹³⁰Ba(n,γ)¹³¹Ba reaction

Abstract

Although k₀-factors and related nuclear data for 122 radionuclides of interest in (n,γ) reactor neutron activation analysis have been tabulated, there are still some reactions attracting interest with respect to the accuracy of the literature data. The present paper deals with the reaction¹³⁰Ba(n,γ)¹³¹Ba, for which a more accurate half-life is proposed, together with re-evaluated Q₀ and k₀ factors. The new values are 11.53 days for T, 21.3 for Q₀, and for the k₀'s 3.90×10⁻⁵, 2.75×10⁻⁵, 1.92×10⁻⁵ and 6.48×10⁻⁵ for the γ-rays at 123.8 keV, 216.1 keV, 373.2 keV and 496.3 keV, respectively.
