We have searched for direct production of scalar top quarks at the
Collider Detector at Fermilab in 88 pb-1 of p anti-p collisions at s**(1/2) = 1.8
TeV. We assume the scalar top quark decays into either a bottom quark and a
chargino or a bottom quark, a lepton, and a scalar neutrino. The event
signature for both decay scenarios is a lepton, missing transverse energy, and
at least two b-quark jets. For a chargino mass of 90 GeV/c2 and scalar
neutrino masses of at least 40 GeV/c2, we find no evidence for scalar top
production and present upper limits on the production cross section in both
decay scenarios.
