Description
The parameters of a linear matrix element have been measured for the η' → ηπ0π0 decay in a high statistical and systematical accuracy experiment performed at the IHEP 70 GeV accelerator. GAMS-2000 hodoscope spectrometer was used to detect six photons from the η' decay. It is shown that the matrix element is practically constant; it depends slightly upon only one of the Dalitz variables
