Abstract
Based on 7.8 x 10(6) J/psi events collected by the BES at BEPC, the ha dronic decays J/psi -->phi pi(+)pi(-) and J/psi-->omega pi(+)pi(-) are studied, and the branching ratios of these process and the mass and w idth of f(0) are obtained, The angular distribution of J/psi --> phi f (0), f(0) --> pi(+)pi(-), is fitted and the helicity amplitude ratios of this process are given for the first time.
