摘要：

In the SND experiment at VEPP-2M e(+)e(-) collider the phi(1020) --> pi(0)pi(0)gamma decay was studied and its branching ratio was measured: B(phi --> pi(0)pi(0)gamma)=(1.221 +/- 0.098 +/- 0.061) . 10(-4). It was shown, that f(0)(980)gamma intermediate state dominates in this decay and the f(0)(980)-meson parameters were obtained. (C) 2000 Elsevier Science B.V. All rights reserved.
