The neutral decay of the η'(958)-meson η' → ωγ → π0γγ → 4γ has been studied. The experiment has been performed in the IHEP 70 GeV accelerator with the multiphoton hodoscope spectrometer GAMS-2000. The measured branching ratio of the η' → ωγ decay (BR = 0.0330 ± 0.0036) is found to be in agreement with theoretical predictions.
