| Abstract
We report the observation of dijet events with a
Double Pomeron Exchange topology produced in antiproton-proton
collisions at 1800 GeV. The events are
characterized by a leading antiproton with a fractional
momentum loss Xi in the range 0.035< Xi <0.095 and a four
momentum transfer squared |t|<1 GeV2, two jets with
transverse energy ET(jet) > 7 GeV in the
central pseudorapidity region, and a rapidity gap,
defined as a region of pseudorapidity devoid of particles,
in the region 2.4< eta <5.9 on the outgoing proton side.
Results on jet kinematics, production rates, and
comparisons with corresponding results from single
diffractive and inclusive dijet production are presented.
