摘要：

From 199ηO → 3πO → 6γ, 526ηO → π+π-πO and 401ηO → γγ events with all γ-rays reconstructed in a heavy liquid bubble chamber, we obtain direct and independent measurements of the branching ratios: R1 = Γ(ηO → 3πO)/Γ(ηO → π+π-πO) = 1.50-0.29 +0.15 and R2 = Γ(ηO → γγ)/Γ(ηO → π+π-πO) = 1.72 ± 0.25. We also study the Dalitz-plots for the modes ηO → 3πO and ηO → π+π-πO, and find no significant variation of the amplitude of the decay ηO → 3πO. © 1969.
