Resumo

During the processing of the data obtained in the space experiment NUCLEON, results were obtained that were of significant astrophysical importance. Using the GALPROP package, the inverse problem of the propagation of cosmic rays from the source (close Supernovae) to the observer was solved, a component spectrum was calculated at the source. It was shown that a systematic change in the power index (slope of the spectrum) was observed at the source, which can be interpreted as incomplete ionization of cosmic rays now of acceleration at the front of the supernova shock wave. Magnetic rigidity spectra analysis was applied for nitrogen nuclei fluxes and the total spectrum of rare nuclei with odd charges from 9 to 19 (F, Na, Al, P, Cl, K). Ratios of odd and even nuclei fluxes are calculated. It turned out that the spectrum of rare, odd nuclei is more rigid than the spectrum of abundant even nuclei (Z = 10–20) at the magnetic rigidity area 300–10 000 GV.
