Model-independent determination of isotopic cross sections per fission for reactor antineutrinos
نویسندگان
چکیده
Model-independent reactor isotopic cross sections per fission are determined by global fits of the antineutrino data from High-Enriched Uranium (HEU) rates, Low-Enriched (LEU) and fuel evolution data. Taking account implicit quasi-linear relationship between fractions $^{239}\rm{Pu}$ $^{241}\rm{Pu}$ in LEU data, Inverse-Beta-Decay (IBD) yields their correlations fissionable isotopes $^{235}\rm{U}$, $^{238}\rm{U}$, Pu's obtained. The data-driven IBD provide an anomaly-free model for fission, where better than 1\% accuracy expected can be achieved future experiments.

Search for Oscillations of Reactor Antineutrinos at Very Short Baselines
Anomalous results from a variety of neutrino experiments, astrophysical observations, and cosmology suggest the possible existence of sterile neutrinos. Most recently, a re-analysis of short-baseline reactor neutrino experiments has revealed a discrepancy between observations and the predicted antineutrino flux. While the spectral shape and uncertainties obtained in this work are comparable to ...

Thehistory ofexperiments on neutrino-induced reactions extends back more than two decades. The early experiments were concerned with establishing the existence of neutrinos t, and later the existence of two different types of neutrinos 2), the' conservation of lepton numbers and the search for intermediate bosons 3'4) . In terms of the current-current weak interaction, the neutrino had been, un...
متن کاملTowards high accurate neutron-induced fission cross sections of 240,242Pu: Spontaneous fission half-lives
Fast spectrum neutron-induced fission cross sections of transuranic isotopes are being of special demand in order to provide accurate data for the new GEN-IV nuclear power plants. To minimize the uncertainties on these measurements accurate data on spontaneous fission half-lives and detector efficiencies are a key point. High -active actinides need special attention since the misinterpretation ...

The neutron-activation method was used for obtaining new experimental data on cross sections both for Ge(n,2n)Ge nuclear reaction and for some other (n,x) reactions on zirconium and germanium isotopes. The neutron generator was used as a neutron source. The samples in a shape of foils of natural germanium and zirconium were irradiated by DTneutrons. The following sources of uncertainties are ta...
