Antineutrino--proton interactions in the 15-foot bubble chamber

From 24,000 pictures of the Fermilab 15-foot hydrogen bubble chamber exposed to a broad band anti $nu$ beam, there were 89 anti $nu$p $Yields$ $mu$$sup +$ + X$sup 0$ events with a total momentum in the charged tracks greater than 5 GeV/c obtained. The techniques used to identify the muon are discussed, and the anti $nu$ energy is estimated. The charged particle multiplicity distributions and the mean $pi$$sup 0$ multiplicity are presented. The semi- inclusive X, Y, Z, Q$sup 2$ and W distributions are compared with model predictions. The rate of strange particle production is measured. No evidence was found for charm particle production. (auth)
