Antiproton-proton annihilation into 0 has been studied with the Crystal Barrel spectrometer at CERN at an incident beam momentum of 1.94 GeV/c. The data were taken with a trigger requiring neutral nal states. A new isovector state, the a2(1660) decaying to 0 , is observed. In the invariant mass region around 2.1 GeV=c 2 , strong production of a heavy resonance is required, but our analysis does not distinguish between J P = 0 + , 2 + and 4 +. The production of the f0(1500) in reactions in ight is also observed.
