Descrição
The diffusion equation of cosmic-ray nucleons is exactly integrated using the successive approximation method for a general distribution of the primary component, and taking into account the rising with energy of the nucleon-air nuclei cross-section. The interaction probability law for the nucleon in the atmosphere is obtained as a consequence of the respective diffusion equation. If the nucleon-air nuclei cross-section rises logarithmically, this probability law assumes a binomial form, and for the constant cross-section it is purely poissonian. We also compared our calculated nucleon intensity with the measured at sea-level: a good consistency is obtained with an average inelasticity coefficient around 0.60.
