Abstract
Fermilab experiment E-760 has confirmed the f2(1520) state in the 3pi0 final state in antiproton-proton annihilations in-flight (approximate ly 3.0 to 3.6 GeV c.m. energy), seen previously by Crystal Barrel and other groups at CERN at rest. The f2(1520) is also seen in its 2pi0 de cay mode in the 2pi0eta channel and 2eta decay mode in the pi(0)2eta c hannel. There are indications of this state in the 3eta decay channel. The invariant mass spectrum is rich in states near 2 GeV, and amplitu de and spin/parity analysis of the Dalitz plot is in progress in this mass region.
