“…The partial γ-ray production cross sections (σ γ ) deduced in this analysis, together with σ 0 , provide essential data for the augmentation of other neutron data libraries, such as the Evaluated Nuclear Data File (ENDF) [8] and the Reference Input Parameter Library (RIPL) [9], which are used in a variety of modeling applications. The thermal cross sections reported in this work are particularly relevant for several areas of societal importance, including: addressing the fallout activity from 181 W in thermonuclear-weapons testing [10][11][12]; the potential use for 181 W as a medical isotope in the treatment of brachytherapy [13]; fusion and accelerator-driven reactor designs based on neutron targets comprising natural TABLE I: Select partial γ-ray production cross sections corresponding to (n, γ) reactions on the major tungsten isotopes.

Radiative thermal neutron-capture cross sections for the 180 W(n, γ) reaction and determination of the neutron-separation energy Prompt thermal neutron-capture partial γ-ray production cross sections were measured for the first time for the 180 W(n, γ) reaction using a cold guided-neutron beam at the Budapest Research Reactor. Absolute 181 W γ-ray cross sections were internally standardized using well-known comparator γ-ray cross sections belonging to the other tungsten isotopes present in the 11.35%-enriched 180 W sample. Transitions were assigned to levels in 181 W based largely upon information available in the literature. The total radiative thermal neutron-capture cross section σ0 was determined from the sum of direct prompt γ-ray cross sections populating the ground state and a modeled contribution accounting for ground-state feeding from the quasi continuum. In this work, we find σ0 = 21.67 (77)
