   Abstract:
   We report a measurement of the fraction of events with a large pseudorapidity gap Delta eta within the pseudorapidity region available to the proton dissociation products X in p-bar+p-->p-bar+X. For a final state p-bar of fractional momentum loss xi p-bar and 4-momentum transfer squared tp-bar within 0.063 is found to be 0.246±0.001 (stat)±0.042 (syst) [0.184±0.001 (stat)±0.043 (syst)]. Our results are compared with gap fractions measured in minimum bias p-barp collisions and with theoretical expectations.
