We have searched for evidence of top quark production in [ital p[bar p]] collisions at [radical][ital s] =1.8 TeV using the [ital D]0 detector at the Fermilab Tevatron collider. For an integrated luminosity of 15 pb[sup [minus]1], we report results of a search for [ital t[bar t]] pairs in the decay modes [ital t[bar t]][r arrow][ital e][mu]+jets,[ital ee]+jets,[ital e]+jets, and [mu]+jets. From analyses of these modes we obtain a lower limit on the top quark mass of 131 GeV/[ital c][sup 2] at the 95% confidence level, assuming standard model branching fractions and a predicted cross section for [ital t[bar t]] production. We discuss the properties of an event for which expected backgrounds are small.
