“…The three-dimensional spatial distribution of primary γ rays is generated using the neutron beam profile for the radial dimension [23] and the neutron absorption probability across the sample thickness, which obviously depends on the particular value of the cross section and, therefore, on neutron energy. In this way, the self-absorption effect of the γ rays in the sample is realistically considered.…”

We have measured the neutron capture reaction yield of 232 Th at the neutron time-of-flight facility n TOF at CERN in the energy range from 1 eV to 1 MeV. The average capture cross section has been extracted in the energy range from 4 keV up to 1 MeV with an overall accuracy better than 4%. An independent IAEA evaluation shows good agreement with the data. The average cross section has been expressed in terms of average resonance parameters using the partial waves = 0, 1, and 2.

“…Regarding the spatial profile of the neutron beam, two collimators placed along the neutron beam line provide a nearly symmetric Gaussian-shaped profile at the sample position. In the eV region the width of this Gaussian profile is ∼5 mm, yielding a total diameter of ∼4 cm [20].…”

The neutron capture cross section of 237 Np was measured between 0.7 and 500 eV at the CERN n_TOF facility using the 4π BaF 2 Total Absorption Calorimeter. The experimental capture yield was extracted minimizing all the systematic uncertainties and was analyzed together with the most reliable transmission data available using the SAMMY code. The result is a complete set of individual as well as average resonance parameters [D 0 = 0.56(2) eV, γ = 40.9(18) meV, 10 4 S 0 = 0.98(6), R = 9.8 (6) (2002)]. The results indicate that a new evaluation combining the present capture data with reliable transmission data would allow reaching an accuracy better than 4%, in line with the uncertainty requirements of the nuclear data community for the design and operation of current and future nuclear devices.
