We have searched for the supersymmetric partner of the top quark
(stop) in 107 pb-1 of p anti-p collisions at s**(1/2) = 1.8 TeV collected by the
Collider Detector at Fermilab (CDF). Within the framework of the Minimal
Supersymmetric extension of the Standard Model (MSSM) each of the
pair-produced stops is assumed to decay into a lepton, bottom quark and
supersymmetric neutino. 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 calculate a
95% confidence level (C.L.) upper limit on the stop production cross
section, which excludes stop masses in the region (80 \leq m_t-bar \leq 135
GeV/c2) in the mass plane of stop versus sneutrino.
