Description
The e+e-→ωπ0→π0π0γ process was investigated in the SND experiment at the VEPP-2M collider. A narrow energy interval near the phi-meson was scanned. The observed cross section reveals, at the level of three standard deviation, the interference effect caused by phi→π0π0γ decay. The cross-section parameters, as well as the real and imaginary parts of the phi-meson related amplitude, were measured
