  We present preliminary results for the search for the top quark in D-Zero in
the electron + jets channel where one of the b quark jets is tagged by means of
a soft muon, using 13.5 pb-1 of data. Standard model decay modes for the top
quark are assumed. We present the resulting top cross section and error as a
function of top mass using this channel combined with the dilepton channel and
the untagged lepton + jets channel . At present, no significant signal for top
quark production can be established.
