The Fermilab fifteen-foot bubble chamber/two-plane External Muon Identifier (EMI) hybrid detector filled with Ne(47% atomic)-H/sub 2/ is exposed to the quadrupole triplet beam (< E/sub ..nu..//sub ..mu../ > = 89 GeV, < E/sub anti ..nu..//sub ..mu../ > = 60 GeV). In 326,000 pictures there are 10,148 neutrino and 1773 antineutrino charged current events with two-plane EMI muon identification and muon momenta > 4 GeV/c. In this sample there are 55 ..mu../sup -/..mu../sup +/X, 11 ..mu../sup -/..mu../sup -/X and 0 ..mu../sup +/..mu../sup +/X candidates with muon momenta > 4 GeV/c. The like-sign events are consistent with background. The opposite-sign dimuons occur at R/sub ..mu.. ..mu../ = 0.35 +- 0.10% of the single muon rate. The ..nu../sub ..mu../-induced ..mu../sup -/..mu../sup +/ rate is 0.20 +- 0.15% below E/sub nu//sub ..mu../ = 100 GeV and 0.50 +- 0.30% above 100 GeV. In the opposite-sign dimuons there are 10 candidates with an associated V/sup 0/ implying 0.76 +- 0.36 neutral strange particle per opposite-sign dimuon event. The production rate, excess of neutral strange particles, and kinematic distributions of the dimuon events are consistent with the charm model predictions. 56 references.
