Abstract (data abstract)
Fermilab-Tevatron. Measurement of the cross section for exclusive gamma-gamma production in PBAR-P collisions at centre of mass energy 1.96 TeV using a data sample of total integrated luminosity of 532 pb-1. The analysis required two electromagnetic shows each with ET & gt; 5 GeV and pseudorapidity in the range -1 to 1 and no other detected particles. Three candidate events are observed.
