Abstract

The differential proton spectra at different atmospheric depths bave been calculated from the recent primary cosmic ray spectrum of Olejniczak, Wdowczyk and Wolfendale by using the conventional phenomenological model after Ashton. The energy dependence of the nucleon nucleus interaction cross section is assumed in the calculations. The estimated proton spectra at atmospheric depths 535, 690, 990 and 1033 gcm-2 fits well the experimental proton spectra of Allkofer and Kraft, Kocharian et al., Fickle and Lamb, Brooke and Wolfendale, Diggory et al. and the results yield an energy dependence of nucleon elasticity in the spectral range 20-100 GeV.
