Abstract
The decay J / psi --> gamma pi degrees pi degrees is studied with 7.0 x 10( 6) produced J / psi events collected by the Beijing Spectrometer (BES) with the trigger mode sensitive to both charged and neutral final state at the Beijing Electron-Positron Collider (BEPC). The evidences for the existence of f(J) (1710) and xi (2230) in this channel are presented, and the corresp onding masses as well as the product branching ratios are obtained.
