Abstract
The RENO experiment reports more precisely measured values of and using live days of data. The amplitude and frequency of reactor electron antineutrino () oscillation are measured by comparing the prompt signal spectra obtained from two identical near and far detectors. In the period between August 2011 and February 2018, the far (near) detector observed 103 212 (850 666) candidate events with a background fraction of 4.8% (2.0%). A clear energy and baseline dependent disappearance of reactor is observed in the deficit of the measured number of . Based on the measured far-to-near ratio of prompt spectra, we obtain and .
