We report the full reconstruction of c mesons through the decay chain cJ/ , J/+-, using data obtained at the Collider Detector at Fermilab in 2.60.2 pb-1 of pp collisions at s =1.8 TeV. This exclusive c sample is used to measure the c-meson production cross section times branching fractions. We obtain B=3.20.4(stat)-1.1+1.2(syst) nb for c mesons decaying to J/ with pT>6.0 GeV/c and pseudorapidity <0.5. From this and the inclusive J/ cross section we calculate the inclusive b-quark cross section to be 12.04.5 b for pTb>8.5 GeV/c and <1. 1993 The American Physical Society.
