Title: Impact of Modular Total Absorption Spectrometer measurements of $β$ decay of fission products on the decay heat and reactor ${\bar{ν}}_{e}$ flux calculation

Abstract

Here, we report the results of a β-decay study of fission products ⁸⁶Br, ⁸⁹Kr, ⁸⁹Rb, ⁹⁰^gsRb, ^90mRb, ⁹⁰Kr, ⁹²Rb, ¹³⁹Xe, and ¹⁴²Cs performed with the Modular Total Absorption Spectrometer (MTAS) and on-line mass-separated ion beams. These radioactivities were assessed by the Nuclear Energy Agency as having high priority for decay heat analysis during a nuclear fuel cycle. We observe a substantial increase in β feeding to high excited states in all daughter isotopes in comparison to earlier data. This increases the average γ-ray energy emitted by the decay of fission fragments during the first 10 000 s after fission of ²³⁵U and ²³⁹Pu by approximately 2% and 1%, respectively, improving agreement between results of calculations and direct observations. New MTAS results reduce the reference reactor ¯ν_e flux used to analyze reactor ¯ν_e interaction with detector matter. The reduction determined by the ab initio method for the four nuclear fuel components, ²³⁵U, ²³⁸U, ²³⁹Pu, and ²⁴¹Pu, amounts to 0.976, 0.986, 0.983, and 0.984, respectively.

Decays of the Three Top Contributors to the Reactor ${\bar{ν}}_{e}$ High-Energy Spectrum, ${}^{92}{Rb}$ , ${}^{96 gs}Y$ , and ${}^{142}{Cs}$ , Studied with Total Absorption Spectroscopy

Journal Article Rasco, B. C. ; Wolińska-Cichocka, M. ; Fijałkowska, A. ; ... - Physical Review Letters

Here, we report total absorption spectroscopy measurements of ⁹²Rb, ⁹⁶^gsY, and ¹⁴²Cs β decays, which are the most important contributors to the high energy ν¯_e spectral shape in nuclear reactors. These three β decays contribute 43% of the ¯νe flux near 5.5 MeV emitted by nuclear reactors. This ν¯_e energy is particularly interesting due to spectral features recently observed in several experiments including the Daya Bay, Double Chooz, and RENO Collaborations. Measurements were conducted at Oak Ridge National Laboratory by means of proton-induced fission of ²³⁸U with on-line mass separation of fission fragments and the Modular Total Absorption Spectrometer.

Journal Article Bernlochner, Florian U. ; Prim, Markus T. ; Robinson, Dean J. - Physical Review D

We revisit the experimental and theoretical status of B → ρl¯ν and B → ωl¯ν decays. We perform a combined fit of averaged spectra from Belle and BABAR measurements with prior light-cone sum rule calculations in order to obtain more precise predictions over the full q² range. The extracted values of |V_ub| from these combined fits exhibit smaller uncertainty compared to previous extractions from B → ρl¯ν and B → ωl¯ν decays, and the central values are found to be smaller than values extracted from B → πl¯ν or inclusive measurements. We use our fit results to obtain more precisemore »« less

Search for mixing-induced $C P$ violation using partial reconstruction of ${\bar{B}}^{0} \to D^{* +} X ℓ^{-} {\bar{ν}}_{ℓ}$ and kaon tagging

Journal Article J. P. Lees - Physical Review D

We describe in detail a previously published measurement of CP violation in B⁰-B¯⁰ oscillations, based on an integrated luminosity of 425.7 fb^-1 collected by the BABAR experiment at the PEPII collider. We apply a novel technique to a sample of about 6 million B¯⁰→D*⁺ℓ^-ν_ℓ¯ decays selected with partial reconstruction of the D*+ meson. The charged lepton identifies the flavor of one B meson at its decay time, the flavor of the other B is determined by kaon tagging. We determine a CP violating asymmetry ACP=(N(B0B0)-N(B¯⁰B¯⁰))/(N(B⁰B⁰)+N(B¯⁰B¯⁰))=(0.06±0.17^+0.38_-0.32)% corresponding to Δ_CP=1-|q/p|=(0.29±0.84^+1.88_-1.61)×10^-3. This measurement is consistent and competitive with those obtained at the Bmore » factories with dilepton events.« less
