AbstractAbstract
[en] The mass spectrum for μ+μ-γ systems, produced in π-p interactions at 25 and 33 Gev/c has been studied. To detect muon pairs and photons a wide-aperture magnetic spectrometer and a hodoscope γ-detector were used. In the mass spectrum a clear peak is seen corresponding to the eta' → μ+μ-γ decay previously not observed. The branching for this decay, 8x10-5, and the muon pair spectrum are in agreement with the eta' formfactor model, based on the vector dominance
