We report on a search for supersymmetric squark and gluino particles in a data sample of 19 pb{sup {minus}1} of p{bar p} collisions at {radical}(s)=1.8 TeV recorded by the Collider Detector at Fermilab. We searched for events containing jets plus appreciable missing transverse energy (E/{sub T}). This signature is indicative of pair production and subsequent decay of squarks and/or gluinos. After all cuts, there are 18 events with E/{sub T}{gt}60 GeV and three jets, and 6 events with E/{sub T}{gt}60 GeV and four jets. These numbers of events are consistent with estimates of standard model processes plus detector-induced background sources. The analysis yields lower limits on gluino and squark masses, based on the predictions from the mnimal supersymmetric extension of the standard model. At the 95{percent} confidence level, we find gluino and squark mass limits up to 216 GeV/c{sup 2}, assuming equal gluino and squark masses, and gluino mass limits up to 173 GeV/c{sup 2}, independent of squark mass. {copyright} {ital 1997} {ital The American Physical Society}
