We present measurements of the bottom-quark production cross sections in ppBAR collisions at square-root s = 1.8 TeV. From the inclusive electron production rate, we have determined the bottom-quark production cross sections to be 1010 +/- 270, 168 +/- 43, 37 +/- 10 nb for the rapidity range of \y(b)\ < 1.0 and the transverse momentum ranges of p(T)b > 15, 23, 32 GeV/c, respectively. In addition, from the associated electron-D0 production rate, we have determined the bottom-quark cross section to be 364 +/- 80(stat) +/- 95(syst) nb for \y(b)\ < 1.0 and p(T)b > 19 GeV/c.

Abstract
We present measurements of the bottom-quark production cross sections in ppBAR collisions at square-root s = 1.8 TeV. From the inclusive electron production rate, we have determined the bottom-quark production cross sections to be 1010 +/- 270, 168 +/- 43, 37 +/- 10 nb for the rapidity range of \y(b)\ < 1.0 and the transverse momentum ranges of p(T)b > 15, 23, 32 GeV/c, respectively. In addition, from the associated electron-D0 production rate, we have determined the bottom-quark cross section to be 364 +/- 80(stat) +/- 95(syst) nb for \y(b)\ < 1.0 and p(T)b > 19 GeV/c.
