Abstract

Using a sample of $3 \times 10^{6}$ $ψ (2 S)$ decays recorded by the CLEO detector, we study three-body decays of the $χ_{c 0}$ , $χ_{c 1}$ , and $χ_{c 2}$ produced in radiative decays of the $ψ (2 S)$ . We consider the final states $π^{+} π^{-} η$ , $K^{+} K^{-} η$ , $p \bar{p} η$ , $π^{+} π^{-} η^{'}$ , $K^{+} K^{-} π^{0}$ , $p \bar{p} π^{0}$ , $π^{+} K^{-} K_{S}^{0}$ , and $K^{+} \bar{p} Λ$ , measuring branching fractions or placing upper limits. For $χ_{c 1} \to π^{+} π^{-} η$ , $K^{+} K^{-} π^{0}$ , and $π^{+} K^{-} K_{S}^{0}$ our observed samples are large enough to indicate the largest contributions to the substructure.
