| Summary: | <p>Using the Crystal Ball Detector at the SPEAR e<sup>+</sup>e<sup>-</sup> 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→γπ<sup>0</sup>, γγρ<sup>0</sup>, and γρ<sup>+</sup>ρ<sup>-</sup>, 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.</p>
