We have carried out a sensitive (> or approx. =5 events/nb) search for narrow p-barp states at the BNL Multiparticle Spectrometer. We found no evidence of narrow p-barp states at 2020 and 2200 MeV in the reaction ..pi../sup -/p..-->..p..pi../sup -/p-barp at 16 GeV/c. We quote 2 upper limits of < or approx. =3 nb for these states in our data. Based on the cross sections of the CERN W experiment at 12 GeV/c and assuming baryon-exchange processes for the production, we should have seen > or approx. =5 s signals at 2020 and 2200 MeV.
