| Popis: | The cosmic-ray muon momentum spectrum and charge ratio up to momenta approx. = 10 TeV/c have been measured with high accuracy. The power index of the differential spectrum of parent mesons at production gradually increases with momentum and becomes 2.87 +- 0.06 in the momentum range 1 to 10 TeV/c. The charge ratio is almost constant at a value of 1.25 +- 0.05 from 0.1 to 10 TeV/c. |
