Abstract:
Cosmic rays with primary energy greater than 100 TeV have the low fluxes. Therefore, the air showers are useful for studying primary cosmic ray particles with higher energies. I considered that a primary proton beam with energies in the range 10^5 < E < 10^8 GeV colliding with an atmospheric nucleus target and producing an air shower with charged secondary particles detectable at low levels in the terrestrial atmosphere.
At ground level, (965 m above sea level), for 10^7 shower size, the calculated results for the total number of muons with energies above 1 GeV, ranges between 0.53 x 10^6 muons and 1.22 x 10^6 muons, in good agreement with the experimental data.
