description Crystal Barrel data on pbarp -> pi sup 0 pi sup 0 are presented. Shapes of angular distributions are similar to data of Dulude et al, but show some systematic disagreements. Absolute normalisations disagree seriously. An amplitude analysis finds two alternative solutions. Both contain a J sup P sup C 2 sup + sup + resonance with M = 2020 +- 40 MeV and GAMMA = 235 +- 70 MeV, tentatively identified as the qbarq sup 3 F sub 2 state. Both solutions also require f sub 4 (2050) and f sub 4 (2300).
