%X We have measured exclusive $\pi^{+}\pi^{-}$ production in proton-antiproton collisions at $\sqrt{s}=$0.9 and1.96 TeV in the Collider Detector at Fermilab. We selected events with exactly two oppositely chargedparticles in $|\eta|<1.3$, with no other particles detected in $|\eta|<5.9$. The central $\pi^{+}\pi^{-}$ wasrequired to have rapidity $|y|<1$. By requiring no other charged particles, these events are dominated bydouble pomeron exchange, which constrains the quantum numbers of the central state. The data showresonance structures attributed to the $f_0$ and $f_2$ mesons. We place upper limits on exclusive$\chi_{c0}\rightarrow\pi^{+}\pi^{-}$ and $\chi_{c0}\rightarrow K^{+}K^{-}$.
