Аннотация:The more accurate original calculations of the atmospheric vertical muon energy
spectra at energies 10**2 - 10**5 GeV have been carried out in terms of DPMJET and VENUS
models. The Gaisser-Honda approximations of the measured energy spectra of primary protons,
helium and nitrogen nuclei have been used. The package CORSIKA has been used to simulate
cascades in the standard atmosphere induced by different primary particles with various fixed
energies E. Statistics of simulated cascades for secondary particles with energies (0.01−1)·E was
increased up to 10**6
. It has been shown that predictions of the DPMJET and VENUS models
for these muon fluxes are below the data of the classical experiments L3 + Cosmic, MACRO
and LVD by factors of ∼ 1.6-1.95 at energies above 102 GeV. It has been concluded that these
tested models underestimate the production of the most energetic secondary particles, namely,
π-mesons and K-mesons, in interactions of the primary protons and other primary nuclei with
nuclei in the atmosphere by the same factors.
