The decay J/psi --> gamma pi(0)pi(0) is studied with 7.0 x 10(6) J/psi events collected in the neutral trigger mode by the Beijing Spectrometer at the Beijing Electron-Positron Collider. Evidence for the existence of f(J)(1710) and xi(2230) in this channel is presented, and the corresponding masses as well as the product branching ratios are obtained. An interpretation of the 5(2230) as a glueball is favored. [S0031-9007(98)06780-5].
