摘要We report new searches for solar axions and galactic axionlike dark matter particles, using the first low-background data from the PandaX-II experiment at China Jinping Underground Laboratory, corresponding to a total exposure of about 2.7 x 10(4) kg day. No solar axion or galactic axionlike dark matter particle candidate has been identified. The upper limit on the axion-electron coupling (g(Ae)) from the solar flux is found to be about 4.35 x 10(-12) in the mass range from 10(-5) to 1 keV/c(2) with 90% confidence level, similar to the recent LUX result. We also report a new best limit from the Fe-57 deexcitation. On the other hand, the upper limit from the galactic axions is on the order of 10(-13) in the mass range from 1 to 10 keV/c(2) with 90% confidence level, slightly improved compared with the LUX.
