- Abstract
This study investigates the use of results from new-generation balloon-borne and satellite instruments and earthbound observatories for quantifying primary nuclei spectra in the Galactic sources. The unique data of these experiments allowed to establish new features in cosmic ray spectra in the GV–sub-PV rigidity region, make it possible to formulate an inverse approach of retrieval the spectra of primary nuclei in cosmic ray sources. We use the non-classical diffusion model of cosmic rays in the inhomogeneous Galaxy as the forward model in the inversion. The main parameters of diffusion model are self-consistently determined from experimental data. The inversion is based on the key element of the forward model solution—the presence of knee in the cosmic ray spectrum. We demonstrate that the average value of the injection index of primary nuclei spectra in sources equals .
