论文摘要

宇宙射线(CR)核光谱中最重要的特征是在几百gV处的光谱硬化。重要的是要了解不同核种类的硬化是否相同,用于构建CR来源和传播模型。在这项工作中,我们收集了主要物种(质子,氦,碳,氧气,氧气,霓虹灯,镁,硅和铁),次生物种(锂,铍,硼,硼,硼和氟)和杂种种类(硝基,含氮,钠,硫化和铝的位置)(少量差异)(含锂,嗜烷,硼酸含量)(含有含量,锂,硼酸含量)(含锂,氯铵,硼酸含量)(含锂,嗜硫酸含量)(含有含量)(含锂,盐酸含量)(含硫酸,盐酸含量)(少量分类)(较大的平衡)(较大的平衡)(比较差异(氧化),光谱硬化的刚度)。结果表明,几百GV处的Cr核光谱硬化具有杂种起源。详细说明,原发性和次级CR核种类的光谱硬化的主要因素不同:前者来自不同种类的CR来源的叠加,而后者来自传播过程。这两个因素都会影响各种CR核光谱,只是具有不同的权重。

The most significant feature in the cosmic-ray (CR) nuclei spectra is the spectral hardening at a few hundred GV. It is important to know whether the hardening of different nuclei species is the same or not for constructing CR sources and propagation models. In this work, we collect the recently released AMS-02 CR nuclei spectra of primary species (proton, helium, carbon, oxygen, neon, magnesium, silicon, and iron), secondary species (lithium, beryllium, boron, and fluorine), and hybrid species (nitrogen, sodium, and aluminum) and study the break positions and the spectral index differences (less and greater than the break rigidity) of the spectral hardening quantitatively. The results show us that the CR nuclei spectral hardening at a few hundred GV has hybrid origins. In detail, the dominating factors of the spectral hardening for primary and secondary CR nuclei species are different: the former comes from the superposition of different kinds of CR sources, while the latter comes from the propagation process. Both of these factors influence all kinds of CR nuclei spectra, just with different weights.
