In a study of the reaction e$sup +$$e$$sup -$$Yields$$gamma$$gamma$ in the region of the psi (3684) resonance, no evidence is found for a deviation from quantum electrodynamics. Limits are also set on the decays psi (3684) $Yields$$pi$$sup 0$$gamma$, psi (3684) $Yields$eta$sup 0$$gamma$, and psi (3684) $Yields$$X$$sup 0$$gamma$, where X$sup 0$ is a pseudoscalar state in the mass range 2500--3000 MeV which subsequently decays into two $gamma$ rays.
