  4. Abstract:
  5. We have simulated more than 105 extensive air showers (EAS) by CORSIKA code, with a proton as the primary particle. The range of energy for primary particles was selected from 50 TeV to 5 PeV, with differential flux given by dN/dE E-2.7. Using the secondary charged particles produced of these EASs, we obtained the function dNsp(θ,X)/dθ, where Nsp(θ,X) is the number of secondary charged particles in EASs as a function of atmosphere depth, X, and zenith angle, θ. A sin θcos n(X)θ distribution was obtained for zenith angle distribution of the number of secondary charged particles, where power index, n(X), is a function of atmosphere depth, X. We obtained n(X)=3.02+0.003Xln X-8.28×10-9X3-1.35ln X. We have compared our results with the experimental data of various observatories. © 2008 The American Physical Society
