Abstract.
The exclusive production of proton-antiproton pairs in the collisions of two quasi-real photons has been studied using data taken at \(\sqrt{s_{ee}} = 183 \) GeV and 189 GeV with the OPAL detector at LEP. Results are presented for \(p\bar{p}\) invariant masses, W, in the range 2.15<W<3.95 GeV. The cross-section measurements are compared with previous data and with recent analytic calculations based on t he quark-diquark model.
