英文摘要A method of determining the p-air inelastic cross section by measuring the directly arrived protons at high altitudes is presented. Its feasibility is studied via a Monte Carlo simulation. Assuming a KASCADE-like hadron calorimeter is set up at the center of the Yangbajing ARGO array, selecting events with air shower (AS) cores hitting the calorimeter, using the full-coverage ARGO array as AS anti-coincidence and using the calorimeter to measure energies of the unaccompanied hadrons, the directly arrived primary protons can be registered with a known efficiency. By the obtained event sample of directly arrived protons the p-air inelastic cross section used in the Monte Carlo can be re-produced with a precision of 1%-2% that demonstrates the feasibility of this approach.
