Abstract :
Antiproton-proton annihilation into π0π0η has been studied with incident beam momenta of 0.6 to 1.94 GeV/c. The main aim is to look for resonances formed by p̄p and decaying into π0π0η. Resonances observed are: two 4++ resonances with mass and width (M, Γ) at (2044, 208) MeV and (2320±30, 220±30) MeV; three 2++ resonances at (2020±50, 220±70) MeV, (2240±40, 170±50) MeV and (2370±50, 320±50) MeV; two 3++ resonances at (2000±40, 250±40) MeV and (2280±30, 210±30) MeV; a 1++ resonance at (2340±40, 340±40) MeV; and two 2−+ resonances at (2040±40, 190±40) MeV and (2300±40, 270±40) MeV.
