Results are presented for the processes gamma gamma to proton antiproton and gamma gamma to lambda antilambda. The cross-section measurements are compared with the recent analytic calculations based on the quark-diquark model predictions. Monte Carlo studies have been done to investigate the PEP-N expectations for the gamma gamma to proton antiproton process.Invited talk at "E+ E- Physics at Intermediate Energies Workshop", SLAC, Stanford, 30 April - 2 May 2001, (W02) 6 pages LaTeXHigh Energy Physics - Experimenttext
