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 theBeijing Electron-Positron Collider (BEPC). The evidences for the existenceof f(J) (1710) and xi (2230) in this channel are presented, and the corresponding masses as well as the product branching ratios are obtained.
