Abstract
The parameters of the Dalitz diagram for the decay η′ → ηπ0 π0 in a generalized and a linear representation were determined by using a statistical sample of 15 × 103 events. A charge-exchange reaction at a momentum of 32 GeV/c was a source of monoenergetic η′ mesons. The experiment was performed with the aid of the GAMS-4π spectrometer.
