We have searched for pair production of the supersymmetric partner of the top quark (stop) in 107 pb^\ensuremath-1 of pp collisions at √(s)=1.8 TeV collected by the Collider Detector at Fermilab (CDF). Each stop is assumed to decay into a lepton, bottom quark, and supersymmetric neutrino. Such a scenario would give rise to events with two leptons, two hadronic jets, and a substantial imbalance of transverse energy. No evidence of such a stop signal has been found. We exclude stop masses in the region (80\ensuremath≤m_\stackrel\texttildelowt\ensuremath≤135 GeV/c2) in the mass plane of stop versus sneutrino.
