摘要：

The parameters of the Dalitz diagram for the decay eta' -> eta pi (0) pi (0) in a generalized and a linear representation were determined by using a statistical sample of 15 x 10(3) events. A charge-exchange reaction at a momentum of 32 GeV/c was a source of monoenergetic eta' mesons. The experiment was performed with the aid of the GAMS-4 pi spectrometer.
