The $\phi(1020)\to\pi^0\pi^0\gamma$ decay
  In the SND experiment at VEPP-2M $e^+e^-$ collider the $\phi(1020)\to\pi^0\pi^0\gamma$ decay was studied and its branching ratio was measured: $B(\phi\to\pi^0\pi^0\gamma)=(1.221\pm 0.098\pm0.061)\cdot10^{-4}$. It was shown, that $f_0(980)\gamma$ intermediate state dominates in this decay and the $f_0(980)$-meson parameters were obtained.
