Abstract A search for massive photon pair production at $$\sqrt s = 63 GeV$$ has been carried out on the data sample previously employed for the electron pair production study. Positive evidence is reported form γγ〉6GeV, with a production cross-section similar to Drell-Yan electron pairs. The ratio γγ/π0π0 was measured to be ∼10−3 for ap T of each γ or γ or π0 above 3 GeV/c.
