Analysis of the Spectral Intensities and Ratios of Electrons and Positrons in Cosmic Rays
摘要：
本文用解析传播模型研究了FERMI、HESS、ATIC和PAMELA仪器对宇宙射线中总电子分量和正电子分数的观测结果，包括离散源和空间光滑源分布。正电子分数在整个能量范围内的~1-100 GeV的嵌套漏盒模型拟合。本文导出了由源直接加速产生的宇宙射线中电子的谱，并讨论了谱中的窄谱特征。
英文摘要：
The observations of the total electronic component and the positron fraction in cosmic rays by the FERMI, HESS, ATIC, and PAMELA instruments are studied with analytical propagation models, both for a set of discrete sources and for a spatially smooth source distribution. The positron fraction over the entire energy range of ~1-100 GeV is shown to fit with the nested leaky box model. We derive the spectrum of electrons in cosmic rays arising from direct acceleration by the sources and discuss the narrow spectral feature in the spectrum.
