Upward throughgoing muons in underground detectors are induced by atmospheric νμ with energies in the 1-104 GeV range. The oscillations of atmospheric muon neutrinos should affect mainly those with energy smaller than Eν∼ 50 GeV, or Eμ≤ 10 GeV . We analyzed the MACRO upward throughgoing muons data set, using the Multiple Coulomb Scattering to estimate the energy Eμ of muons crossing the detector. We analyzed the event distribution for six event subsamples with different values of <ℓν/ Eν>. The event distribution is in agreement with the hypothesis of neutrino oscillations with Δm2 few times 10-3 eV2 and maximum mixing.
