The results are reported of a search for narrow p-barp states in the mass range 1.9 to 2.5 GeV/c/sup 2/ produced in the meson-exchange reaction ..pi../sup +/p..-->..(p-barp)/sub f/ ..delta../sup + +/ at 9.8 GeV/c are reported. This measurement is sensitive to production of the controversial S(1935) meson. It is also sensitive to multiquark exchange leading to the production of four-quark states. We find no evidence for narrow states at the approx.20 nb level.
