Abstract
The cross section of the gamma gamma --> p (p) over bar reaction was m easured at two-photon center-of-mass energy (W-gamma gamma) between 2. 2 and 3.3 GeV, using the two-photon process at an e(+)e(-) collider, T RISTAN. The W-gamma gamma dependence of the cross section integrated o ver a c.m. angular region of \cos theta\ < 0.6 is in good agreement w ith the previous measurements and the theoretical prediction based on diquark model in the high W-gamma gamma region.
