Abstract: This Letter carries out a sensitive (approx.5 events/nb) search for narrow p-barp states at the Brookhaven National Laboratory multiparticle spectrometer. No evidence is found for such states in the mass range 1900-2400 MeV/c/sup 2/ in the reaction ..pi../sup -/p..-->..p..pi../sup -/p-barp at 16 GeV/c. In particular, the p-barp states at 2020 and 2200 MeV/c/sup 2/ previously reported in a CERN ..cap omega..-spectrometer experiment are not observed.
