摘要：

The cosmic-ray muon momentum spectrum and charge ratio up to momenta 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. © 1979 The American Physical Society.
