摘要：

Signal of the rare radiative decay phi --> eta pi(0)gamma was observed in the SND experiment at VEPP-2M electron-positron collider. The result is based on the analysis of data, corresponding to a total integrated luminosity of 4 pb(-1), or 8 . 10(6) phi-mesons produced. The measured branching ratio of phi --> eta pi(0)gamma decay is equal to (0.83 +/- 0.23) . 10(-4). (C) 1998 Published by Elsevier Science B.V. All rights reserved.
