A partial wave analysis of pp̄ → π0π0η′ has been performed using the η′ → π0π0η′ and η′ → γγ decay modes. The data are dominated by an η′ recoiling against the (ππ) S-wave. In addition, a2(1320) → η′π0 is needed. There is evidence for contributions from a0(1450) → η′π0. The branching ratio of a0(1450) → η′π0 with respect to ηπ0 is consistent with the prediction of SU(3).
