摘要:

本文根据NUCLEON空间实验数据,研究了宇宙线核谱与核电荷的关系。首先,我们研究了丰度核磁刚性谱的谱指数与电荷的关系。其次,对电荷区$Z=9\div20$,研究了稀有奇核和丰度偶核的总能谱的差异。利用GALPROP软件包,求解了从源(近超新星)到观测者的CR传播的逆问题,重建了源中的逐分量光谱,并表明源中的光谱指数存在系统的变化。这种变化可以解释为超新星残余激波加速阶段宇宙射线的不完全电离。计算了$Z=9\div20$电荷范围内低丰度奇核和丰度偶核的磁刚性谱之比,表明在300- 10000 ~GV的刚性范围内,奇稀有核的磁刚性谱比丰度偶核的磁刚性谱硬。

英文摘要:

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.
