Assuming that the amplitude for eta'..-->..eta..pi pi.. is dominated by scalar resonances and that the 0/sup + +/ nonet is composed of conventional p-wave qq-bar states with singlet-octet mixing, we obtain predictions for the decay width and Dalitz slope parameter for the decays eta'..-->..eta..pi pi.. and eta'..--> pi pi pi.. which are in excellent agreement with the latest experimental data. The ..pi pi.. and eta..pi.. mass spectra for eta'..-->..eta..pi pi.. are also determined and fit the experimental data quite well. Similar calculations for these decays using a qq-barqq-bar description of the 0/sup + +/ mesons yield results which disagree with experiment.
