Neutrino induced dimuon events were studied for this thesis. This experiment was performed from October 1977 to January 1978 using the Fermilab quadrupole triplet nertrino beam by a collaboration from California Institute of Technology, Fermilab, Norhtwestern University, The University of Rochester, and Rockefeller University. The detector was composed of two different density steel targets and toroidal magnets instrumented with a spark chamber system and scintillation counter. The analysis was based on about 300 dimuon candidates and about 30,000 single muon events within the fiducial volume. The pion and kaon decay background contribution to the dimuon signal were empirically determined by a density extrapolation as a function of several minimum penetration requirements for the second muon. The characteristics of the dimuon events and their rate relative to the single muon events as a function of observed energy are also presented. The experimental results are analyzed in a quark parton model with four quarks (up, down, strange, and charm). The results show qualitative agreement with the charmed particle production hypothesis, but allow the possibility that other mechanisms could also contribute.
