Abstract

Using the Crystal Ball Detector at the SPEAR e⁺e^- storage ring of the Stanford Linear Accelerator Center, several exclusive final states in radiative ψ decays are studied. Signals are observed for the processes ψ→γπ⁰, γγρ⁰, and γρ⁺ρ^-, and an upper limit is placed on the decay rate for ψ→ηη'. Experimental results are discussed in light of previous results in radiative ψ decays, and with respect to theoretical predictions for gluonic mesons.
