摘要

We report partial wave analysis results for $J/\psi \to \gamma K^+ K^-$ based on $7.8 \times 10^6$ BESI $J/\psi$ events, and find $0^{++}$ to be dominant in the $f_J(1710)$ mass region. Some very preliminary results are presented from the $2.2 \times 10^7$ $J/\psi$ events newly collected at the upgraded BES(BESII). Using the world largest $\psi(2S)$ data sample, BES measures branching ratios of $\psi(2S)$ radiative and hadronic decays. The preliminary R values measured by BESII in the 2-5 GeV energy region are also presented.
