摘要：

The program RAPGAP generates events in ep collisions where the electron is scattered on a pomeron P coupled to the proton p. A gap in rapidity between the fast moving proton and the remaining hadronic system is observed. The program is applicable to photoproduction (Q(2) similar or equal to 0) as well as deep inelastic scattering (Q(2) > 0). Different types of hard interaction processes such as gamma*q --> q' and gamma g --> <q(q)over bar > for light and heavy quarks are included. Several options for the parametrisation of the pomeron and its parton density are available within the program. The hadronisation is performed using the LUND string fragmentation model. The Monte Carlo implementaion is described and some phenomenological consequences are discussed.
