An sample of 4 gamma events is analyzed using a kinematic fit constraining two pairs to the pi0 mass. The 2pi0 effective mass distribution is shown. Clear evidence for the Ks and the f2(1270) are revealed. Events for which no 2pi0 fit passes a confidence level test are refit under the constraint of pi0,eta masses. The resulting effective mass plot shows evidence of the a0(980).
