Sea-Level Muon Charge Ratio of Cosmic Rays at High Energies

The charge ratio of cosmic-ray muons with energies up to 1 TeV in the zenith-angle range 68-82 deg has been measured. The data clearly show an enhancement of the charge ratio with increasing energy thus indicating a 'normal' mass composition of galactic cosmic rays.
