Abstract
The properties of events having the topology and kinematic features of double Pomeron exchange are described. The data were taken at the CERN collider at TeV in the UA1 detector. A calorimeter trigger was used to isolate events in which a central cluster of particles was separated from forward particles by large rapidity gaps. The invariant mass of the central cluster (possibly a colliding Pomeron-Pomeron system) covers the range 10-70 GeV/. The dependence of charged particle multiplicity distributions in these double Pomeron events is strikingly different from their dependence in and interactions.
