Comments regarding hierarchical models of cosmic ray origin
Description
Predictions of the leaky-box theory, the closed-galaxy theory, and the mixed-origin two-component model at various energies are compared. In the low-energy range they do not differ significantly. Around 1014eV, as well as in the EAS region, distinctive effective mases of the primaries are expected. Since GAS primaries originate in comparative nearby sources, their composition is not strongly modulated in propagation. This throws doubt on the validity of assumptions of a high-energy extragalactic heavy-primary radiation. (author)
