Charmonium results from BES

Using～14 × 106 ψ(2S) and ～ 58 × 106 J/ψ data collected at BES Ⅱ/BEPC, the branching fraction of ψ(2S) →Ω-(Ω) + is measured with about 5σ statistical significance. The ∧ electric dipole and , decay parameter are studied using the decay J/ψ→∧→ p π+π-. Using (1065±3) × 106 ψ(2S) decays collected at BESⅢ/BEPCⅡ, we have obtained some interesting physics results. The branching fractions of χcJ →π0π0, ηη are measured with precision improved. The mass and width of he(11P1) state, together with the branching fractions of Br(ψ(2S)→π0hc) and Br(hc→rηc) are the first measurements. Surprisingly, the decays of χc1→φφ,ωω, and ωφ are firstly observed in BESⅢ data.
