Top-quark search in the electron + jets channel in proton-antiproton collisions ats=1.8TeV

A search for the top quark in $\overline{p}p$ collisions at a center-of-mass energy of 1.8 TeV using the Collider Detector at Fermilab is described. A study of events selected by requiring an energetic electron, missing transverse energy, and two or more jets excludes at 95% confidence level the standardmodel production and decay of $t\overline{t}$ pairs if the top-quark mass is between 40 and 77 GeV/${\mathit{c}}^2$. The observed electron+multijet data are consistent with $W$-boson production.
