Inelasticity of nucleus-nucleus collisions and composition of high-energy cosmic rays
Journal Article

· Phys. Rev. D; (United States)
Current experiments to determine the chemical composition and energy spectra of primary-cosmic-ray nuclei around 10/sup 14/ eV maximize collecting power by using thin calorimeters of large area that measure primarily the electromagnetic fraction of the energy released when the nucleus interacts. Estimates of this fraction are model-dependent and differ by nearly a factor of 2 for a range of reasonable models. We discuss the consequences of this for composition studies using emulsion chambers.
