Abstract：
Based on 7.8×10 ⁶J/ψ events collected by the BES at BEPC, through study of the hadronic decays J/ψ→φπ ⁺π ^－and J/ψ→ωπ ⁺π ^－, the branching ratios of the processes and the mass positions and the widths of f0 are obtained. The angular distributions of J/ψ→φf ₀,f ₀→π ⁺π ^－, are fitted and the helicity amplitude ratio of this process is first given.
