Abstract

We report the branching ratios of the χ_c2(1³P₂) and χ_c0(1³P₀) charmonium resonances to two photons using event samples collected by Fermilab experiment E835 in the reactions p̄p→χ_c2(1³P₂)[χ _c0(1³P₀)]. Our result for the χ_c2 is B(χ _c2→γγ)=(1.35±0.25±0.12)×10 ^-4. We set a 95% upper limit for the χ_c0 branching ratio B(χ_c0→γγ) at 2.09×10^-4.
