We report the properties of primary cosmic-ray sulfur (S) in the rigidity range 2.15 GV to 3.0 TV based on 0.38×106 sulfur nuclei collected by the Alpha Magnetic Spectrometer experiment (AMS). We observed that above 90 GV the rigidity dependence of the S flux is identical to the rigidity dependence of Ne-Mg-Si fluxes, which is different from the rigidity dependence of the He-C-O-Fe fluxes. We found that, similar to N, Na, and Al cosmic rays, over the entire rigidity range, the traditional primary cosmic rays S, Ne, Mg, and C all have sizeable secondary components, and the S, Ne, and Mg fluxes are well described by the weighted sum of the primary silicon flux and the secondary fluorine flux, and the C flux is well described by the weighted sum of the primary oxygen flux and the secondary boron flux. The primary and secondary contributions of the traditional primary cosmic-ray fluxes of C, Ne, Mg, and S (even Z elements) are distinctly different from the primary and secondary contributions of the N, Na, and Al (odd Z elements) fluxes. The abundance ratio at the source for S/Si is 0.167±0.006, for Ne/Si is 0.833±0.025, for Mg/Si is 0.994±0.029, and for C/O is 0.836±0.025. These values are determined independent of cosmic-ray propagation.

宇宙射线硫的性质和初级宇宙射线碳、氖、镁和硫成分的测定:来自阿尔法磁谱仪的十年结果

我们报告了刚性范围为 2.15 GV 至 3.0 TV 的初级宇宙射线硫 (S) 的特性,基于0.38×106个阿尔法磁谱仪实验 (AMS) 收集的硫核。我们观察到,在 90 GV 以上,S 通量的刚度依赖性与 Ne-Mg-Si 通量的刚度依赖性相同,这不同于 He-CO-Fe 通量的刚度依赖性。我们发现,与N、Na、Al宇宙线相似,在整个刚度范围内,传统的一次宇宙线S、Ne、Mg、C均具有相当大的二次成分,S、Ne、Mg通量为由一次硅通量和二次氟通量的加权和很好地描述,C 通量由一次氧通量和二次硼通量的加权和很好地描述。C、Ne、Mg 和 S 的传统初级宇宙射线通量的初级和次级贡献(甚至Z元素)明显不同于 N、Na 和 Al(奇数Z元素)通量。源丰度比为小号/0.167±0.006, 为了/0.833±0.025, 为了/0.994±0.029, 对于C/0.836±0.025. 这些值是独立于宇宙射线传播而确定的。
