We report here the results of a measurement of the integral energy distribution of the neutrino-induced muon flux deep underground using the Utah neutrino detector. Five neutrino-induced muon candidates have been obtained from the approximately 1O₆ muons which have passed through the detector during 603 days of live operation out of 830 days total elapsed time. By comparing the observed and expected energy distributions we are able to set lower limits on the saturation energy E/sub o/ of the total neutrino-nucleon cross section or, equivalently, on the mass Mw of the intermediate vector boson if scale invariance of the inelastic structure function nu W₂ is assumed. We find at the 1 sigma , 2 sigma , and 3 sigma levels of confidence E₀>320, 80. and 29 GeV or M/sub w/ > 10. 5, and 3 GeV, respectively (auth)
