Abstract：
Decays of both η and η´ provide very useful information in our understanding of low-energy QCD, and experimental signatures for these decays would be extremely helpful at BES-Ⅲ. The rare decays of the η and η´ mesons could serve as a low-energy test of the Standard Model and its beyond. The sensitivities of the measurements of η and η´ decays are discussed at BES-Ⅲ, in which the η and η´ mesons are produced in the ψ decays.
