Abstract: (Elsevier)

In the SND experiment at VEPP-2M e + e − collider the φ (1020)→ π 0 π 0 γ decay was studied. Its branching ratio B ( φ → π 0 π 0 γ )=(1.14±0.10±0.12)·10 −4 was measured. It was shown, that f 0 (980) γ mechanism dominates in this decay. Corresponding branching ratio B ( φ → f 0 γ )=(3.42±0.30±0.36)·10 −4 was obtained.
