A partial wave analysis of the centrally produced π+ π- 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), f0(1500) and fJ(1710) with J = 0 in the S-wave. The ρ(770) is observed dominantly in the P-0-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.
