Abstract The reaction e + e −→ωπ0 near a Φ resonance was studied with a spherical neutral detector at VEPP-2M e + e − collider. Both main modes of decay of a ω meson were investigated: ω→π+π−π0 and ω→π 0γ. The probability of decay Φ→ωπ0 was obtained from the magnitude of the interference wave in the cross section for the reaction e + e −→ωπ0→ π+π−π0π0: B(Φ→ωπ0) = (5.5 −1.4 +1.6 ±0.3) ×10−5. The ratio of the partial widths of the ω meson was obtained from the ratio of the cross sections for the two modes: Γ(ω→π0γ )/Γ(ω→π+π−π0) = 0.0994 ± 0.0036 ± 0.0038.
