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~-π~0, ψ(2S) → π~0 J/ψ, ηJ/ψ, π~0 π~0 J/ψ, anything J/ψ, and ψ(2S) → γχ_(c1),γχ_(c2) → γγ J/ψ. Using 14 million ψ(2S) events, f_0(980)f_0(980) production in χ_(c0) decays and K~*(892)~0 K~*(892)~0 production in χ_(cJ) (J = 0,1,2) decays are observed for the first time, and branching ratios are determined.
