The pbar p -> Ks Ks -> 4pi+/- cross section was measured at incidentantiproton momenta between 0.6 and 1.9 GeV/c using the CERN Low EnergyAntiproton Ring (LEAR). This investigation was part of a systematic study ofin-flight antiproton-proton annihilations into two-neutral-meson final statesin a search for hadronic resonances. A coarse scan of the pbar p -> Ks Ks crosssection as a function of center-of-mass energy between 1.964 and 2.395 GeV/c^2and a fine scan of the region surrounding the Xi(2220) are presented. Upperlimits on the product branching ratio BR(Xi -> pbar p)BR(Xi -> Ks Ks) aredetermined for a wide range of mass and width assumptions based on thenon-observation of the Xi(2220). A rise in the pbar p -> Ks Ks cross section isobserved near 2.15 GeV/c^2, which is consistent with the f2(2150) resonance.Comment: 11 pages, Latex, to be published in Phys Rev D (Oct 97
