The results of total cross section measurements for the nu(mu,)<(nu)ov
er bar (mu)> interactions with isoscalar target in the 3 - 30 GeV ener
gy range have been presented. The data were obtained with the IHEP-JIN
R Neutrino Detector in the ''natural'' neutrino beams of the U-70 acce
lerator. Neutrino fluxes were obtained by averaging the spectra, based
on the calculations with the use of the experimental data on secondar
y particle yields from the target and muon fluxes measurements in 9 ga
ps of the muon filter, as well as the spectra determined from quasi-el
astic events and spectra defined by extrapolating differential distrib
ution d sigma/d gamma in the region gamma = 0. The significant deviati
on from the linear dependence for sigma(tot) versus neutrino energy is
determined in the energy range less than 15 GeV.
