64. Prompt Gamma Spectroscopy Results for the 88Zr(n,γ) Reaction: New Cascade Identifications and Implications for the Anomalous Thermal Neutron Capture Cross Section

Past measurements have suggested that 88Zr(n,γ)89Zr may exhibit an anomalously large thermal neutron absorption cross section, with reported values far exceeding prior expectations and placing it among the largest known thermal capture cross sections for long-lived nuclides. As a neutron-deficient, radioactive isotope that is neither naturally abundant nor a common fission product, 88Zr...

51. Measurement of the Total 40Ar(n,2n)39Ar and 41Ar(n,γ)42Ar Reaction Cross Sections

Abstract: We investigated the production cross section of two long-lived isotopes of argon, $^{39}$Ar (268 y) and 42Ar (33 y), produced respectively by the $^{40}$Ar(n,2n)$^{39}$Ar and the $^{40}$Ar(n,$\gamma$)$^{41}$Ar(n,$\gamma$)42Ar reactions. The radioactive isotope $^{39}$Ar is widely used for dating and tracing groundwater, ocean water, and ice. It is also important for monitoring...

59. 133Cs(n,γ) cross section measurement with DANCE

Esther Leal Cidoncha (Los Alamos National Laboratory)

6/30/26, 3:20 PM

Caesium-133 is an important fission product for burnup credit as it plays a role in the transmutation of $^{135}$Cs. Neutron-induced cross sections in $^{133}$Cs have been investigated in reference [1]. There are no capture cross section data available in EXFOR describing the resonances in the Resolved Resonance Region. As $^{133}$Cs has a high capture cross section, an accurate measurement of...

21. Impact of nuclear data uncertainties to the effective kinetic parameters of VENUS-F used for reactivity measurements

Federico Di Croce (Belgian Nuclear Research Centre SCK CEN)

6/30/26, 3:40 PM

Reactivity measurements in research reactors serve a dual purpose. First, they are essential to ensure safe reactor operation and to evaluate safety margins. Second, they are used to study the reactor responses to applied perturbations and to characterize sample materials. Any of these measurements depends on the description of the reactor transient behavior. Under a number of simplifying...

16. 235U, 237Np and 232Th fission rate traverse measurements at VENUS-F for nuclear data validation and oscillation experiments

Federico Grimaldi (SCK CEN)

6/30/26, 4:30 PM

Nuclear data benchmarking is often oriented towards criticality experiments. While such measurements represent a crucial pillar of the process providing evaluators with insight on the quality of fuel-related nuclear data, these experiments are often less informative about other nuclear data. Local measurements can be considered to gather the needed complementary information. Such experiments...

3. Determination of partial prompt gamma-ray cross-sections induced by fast neutron inelastic scattering using the FaNGaS instrument

Iaroslav Meleshenkovskii

6/30/26, 4:50 PM

Nowadays, there is a huge interest and demand in fast neutron induced cross-section nuclear data for different fields in research and industry, spanning from chemical analysis of various samples to the design and optimization of the evolving technologies in the domain of GEN-IV fast neutron reactor systems and nuclear fusion technologies. Prompt Gamma Analysis based on Inelastic Neutron...
