The cross section for the reaction e/sup +/e/sup -/..-->..eta..gamma../sub arrow-right//sup //sub gammagamma/ in the vicinity of phi(1020) has been measured with the OLYa detector on the VEPP-2M storage ring. The relative probability found for the decay phi..-->..eta..gamma.. is B(phi..-->..eta..gamma..) = 0.9 +- 0.2%.
