Abstract
We report the results of a search for monoenergetic photons in the decay of both theY(1S)- and theY(2S)-meson. Photons converted in the beam tube or the drift chamber inner wall, and photons detected with the barrel shower counters of the ARGUS detector, respectively, have been used in the analysis. No narrow peak is observed in the energy interval 0.5 GeV≦E y≦4.0 GeV.
