Abstract
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 Spectrome ter at the Beijing Electron-Positron Collider. Evidence for the existe nce of f(J)(1710) and xi(2230) in this channel is presented, and the c orresponding masses as well as the product branching ratios are obtain ed. An interpretation of the 5(2230) as a glueball is favored. [S0031- 9007(98)06780-5].
