Inclusive [ital J]/[psi] and [psi](2[ital S]) production has been studied in [ital [bar p]p] collisions at [radical][ital s] =1.8 TeV using 2.6[plus minus]0.2 pb[sup [minus]1] of data taken with the Collider Detector at Fermilab. The products of production cross section times branching fraction were measured as functions of [ital P][sub [ital T]] for [ital J]/[psi][r arrow][mu][sup +][mu][sup [minus]] and [psi](2[ital S])[r arrow][mu][sup +][mu][sup [minus]]. In the kinematic range [ital P][sub [ital T]][gt]6 GeV/[ital c] and [vert bar][eta][vert bar][le]0.5 we get [sigma]([ital [bar p]p][r arrow][ital J]/[psi] [ital X])[ital B]([ital J]/[psi][r arrow][mu][sup +][mu][sup [minus]]) =6.88[plus minus]0.23(stat)[sub [minus]1.08][sup +0.93](syst) nb, and [sigma]([ital [bar p]p][r arrow][psi](2[ital S])[ital X])[ital B]([psi](2[ital S])[r arrow][mu][sup +][mu][sup [minus]]) =0.232[plus minus]0.051(stat)[sub [minus]0.032][sup +0.029](syst)nb. From these values we calculate the inclusive [ital b]-quark production cross section.
