The {bar p}p{r_arrow}K{sub S}K{sub S}{r_arrow}4{pi}{sup {plus_minus}} cross section was measured at incident antiproton momenta between 0.6 and 1.9 GeV/c using the CERN Low Energy Antiproton Ring. This investigation was part of a systematic study of in-flight antiproton-proton annihilations into two-neutral-meson final states in a search for hadronic resonances. A coarse scan of the {bar p}p{r_arrow}K{sub S}K{sub S} cross section as a function of center-of-mass energy between 1.964 and 2.395 GeV/c{sup 2} and a fine scan of the region surrounding the {xi}(2220) are presented. Upper limits on the product branching ratio B({xi}{r_arrow}{bar p}p){times}B({xi}{r_arrow}K{sub S}K{sub S}) are determined for a wide range of mass and width assumptions based on the nonobservation of the {xi}(2220). A rise in the {bar p}p{r_arrow}K{sub S}K{sub S} cross section is observed near 2.15 GeV/c{sup 2}, which is consistent with the f{sub 2}(2150) resonance. {copyright} {ital 1997} {ital The American Physical Society}
