论文摘要
我们报告了使用119天的反应器打开的I-235与立体声检测器的裂变对抗肿瘤速率的测量。在我们的分析中，我们执行了几个详细的校正，并在反应堆上使用高度富集的U-235燃料实现了最精确的单个测量。我们测量$σ_f$ =（6.34 $ \ pm $ 0.06 [stat] $ \ pm $ \ pm 0.15 [sys] $ \ pm $ 0.15 [型号]）$ \ times $ \ times $ 10 $ {}^{ - 43} $ cm $ $ $ $ $ {2} $ 0.8与模型相比，$ \ pm $ 2.3 [sys] $ \ pm $ 2.3 [型号]）％，与世界平均水平的赤字一致。测试U-235作为赤字的唯一来源，我们发现低较低和高度富集的U-235燃料的2.1标准偏差之间存在张力。
We report a measurement of the antineutrino rate from the fission of U-235 with the STEREO detector using 119 days of reactor turned on. In our analysis, we perform several detailed corrections and achieve the most precise single measurement at reactors with highly enriched U-235 fuel. We measure an IBD cross section per fission of $σ_f$ = (6.34 $\pm$ 0.06 [stat] $\pm$ 0.15 [sys] $\pm$ 0.15 [model]) $\times$ 10${}^{-43}$ cm${}^{2}$/fission and observe a rate deficit of (5.2 $\pm$ 0.8 [stat] $\pm$ 2.3 [sys] $\pm$ 2.3 [model])% compared to the model, consistent with the deficit of the world average. Testing U-235 as the sole source of the deficit, we find a tension between the results of lowly and highly enriched U-235 fuel of 2.1 standard deviations.
