Using data from the Fermilab 15 ft hydrogen bubble chamber, we have studied inclusive ϱ 0 production in antineutrino-proton charged-current interactions. We measure (0.21 ± 0.03) ϱ 0/event, corresponding to ϱ 0/ π −=0.12 ± 0.02. As a function of Q 2 and for hadronic masses above a threshold region, the ϱ 0/ π − ratio shows little variation. At least 50% of the ϱ 0's are consistent with coming from the current fragmentation region. The results agree reasonably well with the predictions of the quark fragmentation model of Feynman and field.
