  In this paper the dependence of the spectra of cosmic ray nuclei on the
charges of nuclei was studied, according to the data of the NUCLEON space
experiment. First, we studied the dependence of the spectral index of magnetic
rigidity spectra on the charge for abundant nuclei. Secondly, for the charge
range $Z=9\div20$, the differences in the total spectra of rare odd and
abundant even nuclei were studied. Using the GALPROP package, the inverse
problem of CR propagation from a source (near supernova) to an observer was
solved, a component-by-component spectrum in the source was reconstructed, and
it was shown that a systematic change in the spectral index in the source
exist. It is supposed that this change may be interpreted as incomplete
ionization of cosmic rays at the stage of acceleration in the supernova remnant
shock. The ratio of the total spectra of magnetic rigidity for low-abundance
odd and abundant even nuclei from the charge range $Z=9\div20$ is obtained, and
it was shown that the spectra of odd rare nuclei are harder than the stpectra
of abundat even nuclei in the rigidity range 300--10000~GV.
