Our study shows that a single Galactic component with subsequent energy cut-offs in the individual spectra of different elements, optimised to explain the observed elemental spectra below similar to 10(14) eV and the “knee” in the all-particle spectrum, cannot explain the observed all-particle spectrum above similar to 2 x 10(16) eV.
