In this paper the dependence of the spectra of cosmic ray nuclei on thecharges of nuclei was studied, according to the data of the NUCLEON spaceexperiment. First, we studied the dependence of the spectral index of magneticrigidity spectra on the charge for abundant nuclei. Secondly, for the chargerange $Z=9\div20$, the differences in the total spectra of rare odd andabundant even nuclei were studied. Using the GALPROP package, the inverseproblem of CR propagation from a source (near supernova) to an observer wassolved, a component-by-component spectrum in the source was reconstructed, andit was shown that a systematic change in the spectral index in the sourceexist. It is supposed that this change may be interpreted as incompleteionization of cosmic rays at the stage of acceleration in the supernova remnantshock. The ratio of the total spectra of magnetic rigidity for low-abundanceodd and abundant even nuclei from the charge range $Z=9\div20$ is obtained, andit was shown that the spectra of odd rare nuclei are harder than the stpectraof abundat even nuclei in the rigidity range 300--10000~GV.
