Altitude variation of cosmic ray nucleons derived from feynman scaling hypothesis

Abstract

The differential proton spectra at different atmospheric depths and the differential neutron spectrum at sea level have been calculated using the scaling hypothesis of Feynman for hadronic inclusive reaction at high energies. In evaluating such values we used the primary nucleon spectrum of Grigorov et al. It is found that the derived spectra fit well the experimental data given by different authors. The estimated neutron-proton flux ratio against atmospheric depths is in accord with the measured data surveyed by Aguirre.
