Abstract
We report on the first measurement of the flux of upgoing muons result ing from interactions of atmospheric neutrinos in the rock below MACRO . The ratio of the observed to the expected number of events integrate d over all nadir angles is 0.73 +/- .09(stat) +/- 0 .06(sys) +/- 12(th eor.). The flux of upgoing muons as a function of nadir angle is prese nted and compared to Monte Carlo expectations. At the 90% confidence l evel, the data are consistent with no neutrino oscillations or some po ssible oscillation hypotheses with the parameters suggested by the Kam iokande contained-event analysis.
