Abstract

Cross sections for proton inelastic collision with different nuclei are described within the Glauber approximation. The significant difference between approximate ``Glauber'' formula and exact calculations with geometrical scaling assumption is shown for very high energy cross section calculations. According to obtained results values of proton-proton cross section reported by the Akeno and Fly's Eye experimental groups are about 10 % overestimated.
