Using data accumulated with the CLEO detector corresponding to an integrated luminosity of L=5.63 pb-1 on the peak of the ψ(2S) [3.08×106 ψ(2S) decays] and 20.70 pb-1 at √s=3.67 GeV, we report first measurements of the branching fractions for the following 13 decay modes of the ψ(2S): η3π, η′3π, ρK+K-, K+K-π+π-π0, 2(K+K-), 2(K+K-)π0, ρpp̅ , pp̅ π+π-π0, ηpp̅ , pp̅ K+K-, ΛΛ̅ π+π-, Λp̅ K+, and Λp̅ K+π+π-, and more precise measurements of 8 previously measured modes: 2(π+π-), ρπ+π-, 2(π+π-)π0, ωπ+π-, K+K-π+π-, ωK+K-, ϕK+K-, and pp̅ π+π-. We also report new branching fraction measurements of ϕπ+π- and ωpp̅ and upper limits for ηπ+π-, ηK+K-, and ϕpp̅ . Results are compared, where possible, with the corresponding J/ψ branching ratios to provide new tests of the 12% rule.
