Muons in air showers at the Pierre Auger Observatory: Mean number in highly inclined events
Original language description
We present the first hybrid measurement of the average muon number in air showers at ultrahigh energies, initiated by cosmic rays with zenith angles between 62 degrees and 80 degrees. The measurement is based on 174 hybrid events recorded simultaneouslywith the surface detector array and the fluorescence detector of the Pierre Auger Observatory. The muon number for each shower is derived by scaling a simulated reference profile of the lateral muon density distribution at the ground until it fits the data. A 10(19) eV shower with a zenith angle of 67 degrees, which arrives at the surface detector array at an altitude of 1450 m above sea level, contains on average (2.68 +/- 0.04 +/- 0.48(sys)) x 10(7) muons with energies larger than 0.3 GeV. The logarithmic gain d lnN mu/d ln E of muons with increasing energy between 4 x 10(18) eV and 5 x 10(19) eV is measured to be (1.029 +/- 0.024) 0.030(sys)).
