We present data on p ̄ p→3π 0 at nine p̄ momenta from 600 to 1940 MeV/c. This process is dominated by the f 2 (1270) π 0 channel, where we observe I =1 resonances with the following masses and widths: 4 ++ (2260±15), Γ =180±20 MeV, 4 ++ (2005±25), Γ =360±80 MeV, 3 ++ (2310±40), Γ =180 +120 −60 MeV, 3 ++ (2070±20), Γ =170±40 MeV, 2 ++ (2280±30), Γ =280±50 MeV, 2 ++ (2100 +10 −30 ), Γ =360 +40 −100 MeV, 1 ++ (2100±20), Γ =300 +30 −60 MeV, and 1 ++ (2340±40), Γ =230±70 MeV.
