摘要：

Rare radiative decay phi --> eta pi(0)gamma was studied with SND detector at VEPP-2M electron-positron collider and its branching ratio was measured: B(phi --> eta pi(0)gamma) = (0.88 +/- 0.14 +/- 0.09) . 10(-4). Significant contribution of the a(0)(980)gamma intermediate state was observed in the decay. The result is based on total integrated luminosity corresponding to 2.10(7) produced phi mesons.
