Abstract
The NEOS detector take data from August 2015 to May 2016. The energy resolution of the detector is about 5% at 1 MeV and the ratio of signal to background is about 23. PSD is used to reduce backgrounds and it reduces more than 70% of backgrounds. The prompt energy spectrum was compared to the two models and the 5 MeV excess is first confirmed at short baseline. There is no strong evidence of light sterile neutrino with 3+1 hypothesis and region of low mass squared difference Δm2 41 in allowed region of Reactor Antineutrino Anomaly[1] is disfavored. © 2019 IOP Publishing Ltd.
