Description
We have identified 262 doubly tagged two-photon events. A subset of the data shows an enhancement of 21 events in the inclusive two-photon mass squared distribution between 0.8 and 2.2 GeV2. If these events result from spin 2 resonance production then GAMMAsub(γ)sub(γ) = 9.5 +- 3.9 +- 2.4 keV (statistical and systematic). From another subset of 58 events in which the final state could be classified we determine the two-photon hadron to muon cross section ratio Rsub(γ)sub(γ) = 1.1 +- 0.3 +- 0.3. (orig.)
