| 英文摘要 | Abstract a new measurement of the reactor antineutrino flux and energy spectrum by the daya bay experiment is reported. with a live time of 621 days, more than 1.2 million inverse beta decay (ibd) candidates were collected by eight antineutrino detectors (ads) deployed in two near (560 m and 600 m flux-weighted baselines) and one far (16400 m flux-weighted baseline) underground experimental halls. the ibd yield was measured and the ratio to the predicted flux using the huber+mueller (ill+vogel) model was determined to be 0.946 ± 0.020 (0.992 ± 0.021). a 2.9 σ deviation was found in the measured ibd positron energy spectrum compared to the predictions. in particular, an excess of events in the region of 4-6 mev was found with a local significance of 4.4 σ. |
