AbstractAbstract
[en] A partial wave-amplitude analysis of the angular distributions in the reaction anti pp → π0π0 at 25 energies was performed. The range of center of mass energies covered is from 2.12 to 2.43 GeV and includes the so-called T- and U-meson regions. A resonance is found in the J/sup PC/I/sup G/ = 2++0+ state in the vicinity of the T (2.15 GeV) and data are consistent with an additional resonance of 4++0+ at the U (2.35 GeV). An isospin decomposition utilizing these data in conjunction with those from anti pp → π+π- reveals possible difficulties in interpretation. 25 references
