A partial wave analysis of the centrally produced π0π0 channel has been performed in pp collisions using an incident beam momentum of 450 GeV/c. An unambiguous physical solution has been found. Evidence is found for the f0(980), f0(1300) and f0(1500) in the the S-wave, and the f2(1270) is observed dominantly in the D-0-wave. In addition, there is evidence for a broad enhancement in the D-wave below 1 GeV.
