Scientific paper

The homogeneous and diffusion models of the origin of cosmic rays are considered with reference to the difference between them and their applicability to cosmic-ray studies. It is shown that, in the interpretation of data on the chemical composition of cosmic rays, while yielding approximately the same values of the basic parameters for stable nuclei (source power, content of different nuclei in the sources, mean pathlength through the matter), the two models differ strongly in the description of radioactive nuclei. Although the use of diffusion halo models is connected with some difficulties and uncertainties, such models reflect the existing concepts of the generation and behavior of cosmic rays. The homogeneous models are shown to be inadmissible.
