This paper reports the measurement of the [ital B] meson and [ital b] quark cross sections through the decay chain [ital B][sup 0][r arrow][ital J]/[psi] K[sup *](892)[sup 0], [ital J]/[psi][r arrow][mu][sup +][mu][sup [minus]], [ital K][sup *](892)[sup 0][r arrow][ital K][sup +][pi][sup [minus]], using 4.3 pb[sup [minus]1] of data collected at the Collider Detector at Fermilab in [ital [bar p]p] collisions at [ital qrts]=1.8 TeV. We obtain [sigma][sub [ital B]]=1.5[plus minus]0.7(stat)[plus minus]0.6(syst) [mu]b for [ital B][sup 0] mesons with transverse momentum [ital P][sub [ital T]][gt]9.0 GeV/[ital c] and rapidity [vert bar][ital y][vert bar][lt]1.0. Using this result, we find [sigma][sub [ital b]]=3.7[plus minus]1.6(stat)[plus minus]1.5(syst) [mu]b for [ital b] quarks with [ital P][sub [ital T]][gt]11.5 GeV/[ital c] and rapidity [vert bar][ital y][vert bar][lt]1.0. The [ital b] quark cross section is compared to next-to-leading order QCD calculations and previous measurements.
