and π0η′ from 600 to 1940 MeV/c

Data taken with the Crystal Barrel detector on p p→π 0 η and π 0 η ′ are presented at p momenta from 600 to 1940 MeV/c. A partial wave analysis finds two alternative solutions, one significantly preferred over the other. Both contain resonances of similar masses and widths, but different coupling constants and phases. The favoured solution contains a J PC =0 ++ resonance at 2025±30 MeV with Γ =330±75 MeV, and three 2 ++ resonances as follows: (i) at 1990 +15 −30 MeV with Γ =190±50 MeV (dominantly 3 P 2 ), (ii) at 2060±20 MeV with Γ =195±30 MeV (dominantly 3 F 2 ), (iii) at 2265±20 MeV with Γ =235 +60 −35 MeV (dominantly 3 F 2 ), There are two 4 ++ resonances at 2025±40 MeV with Γ =250 +80 −55 MeV and at 2300±20 MeV with Γ =230±40 MeV. Errors cover systematic errors and statistical fluctuations of 3 σ .
