Fluxes of cosmic-ray muons were estimated over the energy range extending up to 10{sup 10} GeV. Data on the production of pions; kaons; {eta}, {eta} Prime , {rho}, {omega}, and {phi} mesons; charmed particles; and J/{psi} mesons from accelerator experiments devoted to studying interactions between nucleons and nuclei of air atoms up to nucleon energies of about 2 Multiplication-Sign 10{sup 4} GeV were used in respective calculations. At higher energies, use was made of the results obtained by calculating cross sections for the production of charmed particles and J/{psi} mesons on the basis of QCD models. It is shown that, in interpreting experimental data on extensive air showers, the production of both charmed particles and J/{psi} mesons in the Earth's atmosphere must be taken into account.
