    We have measured the fraction of J/ψ mesons originating from χc meson decays in p p̄ collisions at √s = 1.8 TeV. The fraction, for PTJ/ψ > 4.0 GeV/c and |ηJ/ψ| < 0.6, not including contributions from b flavored hadrons, is 29.7% ± 1.7%(stat) ± 5.7%(syst). We have determined the cross sections for J/ψ mesons originating from χc decays and for directly produced J/ψ mesons. We have found that direct J/ψ production is in excess of the prediction of the color singlet model by the same factor found for direct ψ(2S) production.
