Abstract
The radiative decay has been studied with data taken with the crystal-ball detector at the SPEAR storage ring. In addition to the well-known , the mass spectrum shows a broad enhancement centered at ∼ 1700 MeV. The authors have searched for the in the mass spectrum and find (90% confidence level).
