Abstract

The inelastic cross section of p-air collisions [σin(p-air)] between 1016 and 1018 eV is estimated by the observation of extensive air showers at Akeno. The flux of air showers at different zenith angles is analyzed with both a fixed muon number and a fixed electron number. σin(p-air) increases with energy as 290×Elab0.06±0.01 mb (Elab in teraelectron-volts) up to 1018 eV with the assumptions of Feynman scaling in the fragmentation region and at least 10% of the primary particles being protons.
