摘要：

We report on an experimental performed at DESY to search for the πo + γ decay of the φ mesons, photoproduced at 5.5 GeV on a Zn target. From the known production cross-section and the calculated detection efficiency, an upper limit for the branching ratio B = Γ(φ → πo + γ) Γ(φ → all) of 0.35% was obtained. © 1969.
