Description
The charged meson momentum spectra from anti pp annihilation at rest have been measured with high statistics. A search is made for structures between 150 and 300 MeV/c which might indicate narrow baryonium states. We find four narrow lines which are identified with the absorption and decay processes of kaons stopping in the target. No other narrow structure are seen, giving limits of 2-6x10-4/anti p (90% CL) for the yield of a narrow state in the mass range 1510-1660 MeV. (orig.)
