Ultra high energy cosmic rays: implications of Auger data for source spectra and chemical composition
Ultra high energy cosmic rays: implications of Auger data for source spectra and chemical composition
We use a kinetic-equation approach to describe the propagation of ultra high energy cosmic ray protons and nuclei and calculate the expected spectra and mass composition at the Earth for different assumptions on the source injection spectra and chemical abundances. When compared with the spectrum, the elongation rate $X_{max}(E)$ and …
