主　　题：moment. excess estimates 

摘      要：We report a search for new physics signals using the low energy electron recoil events in the complete data set from PandaX-Ⅱ,in light of the recent event excess reported by XENON1 *** data correspond to a total exposure of 100.7 ton·day with liquid *** robust estimates of the dominant background spectra,we perform sensitive searches on solar axions and neutrinos with enhanced magnetic *** is found that the axionelectron coupling gAe4.6×10^(-12) for an axion mass less than 0.1 keV/c^(2) and the neutrino magnetic moment μv4.9×10^(-11)μB at 90%confidence *** observed excess from XENON1 T is within our experimental constraints.
