A study of f0(1500) decays into 4π in at rest

Crystal Barrel data on at rest are presented. Mass spectra for 2π⁰ combinations, 3π⁰ and 4π⁰ and decay angular distributions all differ significantly from phase space. We present several ways of fitting the data. All agree on the definite presence of the f₀(1500), observed in its 4π⁰ decay mode. It can decay into ππ(1300) and into σσ where σ stands for the full ππ S-wave amplitude.
