| Abstract: | We study the production of an isolated large- photon as well as the production of an isolated prompt photon plus a jet in collisions. Our results are obtained by a NLO Monte Carlo program of partonic event generator type. We discuss the possibilities to constrain the parton densities in the real photon and compare to preliminary OPAL data.
