Abstract:	摘要： This Letter reports a measurement of the flux and energy spectrum of electron antineutrinos from six 2.9 GWth nuclear reactors with six detectors deployed in two near (effective baselines 512 and 561 m) and one far (1579 m) underground experimental halls in the Daya Bay experiment. Using 217 days of data, 296 721 and 41 589 inverse β decay (IBD) candidates were detected in the near and far halls, respectively. The measured IBD yield is (1.55±0.04) ×10(-18) cm(2) GW(-1) day(-1) or (5.92±0.14) ×10(-43) cm(2) fission(-1). This flux measurement is consistent with previous short-baseline reactor antineutrino experiments and is 0.946±0.022 (0.991±0.023) relative to the flux predicted with the Huber-Mueller (ILL-Vogel) fissile antineutrino model. The measured IBD positron energy spectrum deviates from both spectral predictions by more than 2σ over the full energy range with a local significance of up to ∼4σ between 4-6 MeV. A reactor antineutrino spectrum of IBD reactions is extracted from the measured positron energy spectrum for model-independent predictions. 其他題名： Phys Rev Lett 出版者： United States: American Physical Society (APS) 出版日期： 2016-02-12 出處： Physical Review Letters, 2016-02, Vol.116 (6), p.061801, Article 061801 資源來源： American Physical Society Journals 識別號： ISSN: 0031-9007 識別號： ISSN: 1079-7114 識別號： ISSN: 1092-0145 識別號： EISSN: 1079-7114 識別號： DOI: 10.1103/physrevlett.116.061801 識別號： PMID: 26918980
