Abstract: (arXiv)

The decays

J/\psi \rightarrow \gamma \pi^+\pi^-\pi^0

and

J/\psi \rightarrow \gamma \pi^0\pi^0\pi^0

are analyzed using a sample of 225 million \jpsi events collected with the BESIII detector. The decay of \eta(1405)\ar f_{0}(980)\pi^0 with a large isospin violation is observed for the first time. The width of the

f_{0}(980)

observed in the dipion mass spectra is anomalously narrower than the world average. Decay rates for three-pion decays of the

\eta'

are also measured precisely.
