- Аннотация: Results of great astrophysical importance are obtained in processing data collected in the NUCLEON space experiment. The GALPROP package is used to solve the inverse problem of cosmic ray(CR) propagation from a source (a nearby supernova) to the observer. A component-by-component spectrumof the source is plotted, and a systematic change in its spectral index is revealed. This can be interpreted as incomplete ionization of cosmic rays at the moment they are accelerated at the front of the supernova’s shock wave. Fluxes of nitrogen nuclei and the total spectrum of rare nuclei with odd charges of 9 to 19 (F, Na, Al, P, Cl, K) are investigated in analyzing the spectra in terms of magnetic rigidity. The ratios of the flows of odd and even nuclei are plotted. The spectrum of rare odd nuclei is found to be harder than that of abundant even nuclei (Z = 10–20) in the 300–10000 GV range of magnetic rigidities.
