Results are reported based on samples of 58 million J/ψ and 14 million
ψ(2S) decays obtained by the BESII experiment. Improved branching fraction
measurements are determined, including branching fractions for
J/ψ→π+π−π0, ψ(2S)→π0J/ψ, ηJ/ψ, π0π0J/ψ, anything J/ψ, and
\psi(2S)\to\gamma\chi_{c1},\gamma\chi_{c2}\to\gamma\gamma\jpsi. Using 14
million ψ(2S) events, f0​(980)f0​(980) production in χc0​ decays
and K∗(892)0Kˉ∗(892)0 production in χcJ​ (J=0,1,2) decays are
observed for the first time, and branching ratios are determined.Comment: Parallel Talk presented at ICHEP04. 4 pages and 6 figure
