Abstract
The attenuation length of proton primaries and the proton-air inelastic cro ss section are studied at energies E-0 approximate to 10(15) eV by using th e EAS-TOP array data. Proton initiated Extensive Air Showers, in the energy range (2 divided by 4) 10(15) eV and near maximum development, are selecte d from their N-mu(E-mu > 1 GeV) and N-e sizes. The experimental attenuation length Lambda(obs) is compared with those obtained from simulations, inclu ding the full detector response, based on different interaction models (HDP M, VENUS, DPMJET, QGSJET and SIBYLL) in the frame of CORSIKA code. The prot on-air inelastic cross section is also inferred by using the factor k = Lam bda(obs)(sim)/lambda(p-air)(sim) obtained from each interaction model.
