摘要:

本文介绍了对2002-2003年在南极进行的ATIC-2气球实验的质子、He、C、O、Ne、Mg、Si和Fe原子核的能谱、所有粒子的能谱以及原始宇宙射线原子量的平均对数作为能量函数的数据进行处理的最终结果。最后的结果是基于改进的方法使用较早,特别是,大大提高了分辨率的电荷谱。证实了质子和氦核谱的显著差异(质子谱较陡)以及质子和重核谱的非幂次特性(能量大于10 TeV时碳谱变平)的初步结论。发现了原子量平均对数能量依赖性的复杂结构。

英文摘要:

The final results of processing the data from the balloon-born experiment ATIC-2 (Antarctica, 2002-2003) for the energy spectra of protons and He, C, O, Ne, Mg, Si, and Fe nuclei, the spectrum of all particles, and the mean logarithm of atomic weight of primary cosmic rays as a function of energy are presented. The final results are based on improvement of the methods used earlier, in particular, considerably increased resolution of the charge spectrum. The preliminary conclusions on the significant difference in the spectra of protons and helium nuclei (the proton spectrum is steeper) and the non-power character of the spectra of protons and heavier nuclei (flattening of carbon spectrum at energies above 10 TeV) are confirmed. A complex structure of the energy dependence of the mean logarithm of atomic weight is found.
