  A partial wave analysis of the centrally produced pi+pi- 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 the S-wave. The
rho(770) is observed dominantly in the P0-wave and the f2(1270) is observed
dominantly in the D0-wave. In addition, there is evidence for a broad
enhancement in the D-wave below 1 GeV.
