Inelasticity inp-nucleus collisions and its application to high energy cosmic-ray cascades

Abstract
We employ a simple multiple scattering model to investigate the inclusive reaction p+Ap+X for projectile momenta in the 100200GeV/c range. We find that data are consistent with a class of interaction models in which the stopping power of nuclei is rather low. We discuss extrapolation to ultrahigh energy and the application to interpretation of cosmic-ray air showers at energies up to 1020eV.
