Anomalies in the Charge Yields of Fission Fragments from the ${}^{238}{U (n, f)}$ Reaction

Journal Article Wilson, J. N. ; Lebois, M. ; Qi, L. ; ... - Physical Review Letters

Fast-neutron-induced fission of ²³⁸U at an energy just above the fission threshold is studied with a novel technique which involves the coupling of a high-efficiency γ-ray spectrometer (MINIBALL) to an inverse-kinematics neutron source (LICORNE) to extract charge yields of fission fragments via γ-γ coincidence spectroscopy. Experimental data and fission models are compared and found to be in reasonable agreement for many nuclei; however, significant discrepancies of up to 600% are observed, particularly for isotopes of Sn and Mo. This indicates that these models significantly overestimate the standard 1 fission mode and suggests that spherical shell effects in the nascent fissionmore »« less

Effects of fission yield data in the calculation of antineutrino spectra for ${}^{235}U (n, fission)$ at thermal and fast neutron energies

Journal Article Sonzogni, A. A. ; McCutchan, E. A. ; Johnson, T. D. ; ... - Physical Review Letters

Fission yields form an integral part of the prediction of antineutrino spectra generated by nuclear reactors, but little attention has been paid to the quality and reliability of the data used in current calculations. Following a critical review of the thermal and fast ENDF/B-VII.1 ²³⁵U fission yields, deficiencies are identified and improved yields are obtained, based on corrections of erroneous yields, consistency between decay and fission yield data, and updated isomeric ratios. These corrected yields are used to calculate antineutrino spectra using the summation method. An anomalous value for the thermal fission yield of ⁸⁶Ge generates an excess of antineutrinosmore »« less
