论文摘要
当前的宇宙射线（CR）光谱数据的精确度使我们能够精确测试有关银河系中带电颗粒的简单模型。但是，我们的研究受到与CR相互作用的横截面相关的不确定性的严重限制。因此，我们开发了一组新的横截面，这些横截面源自Fluka Monte Carlo Code，该截面是针对CR相互作用的治疗而优化的。我们显示了这些横截面，以及它们在CR繁殖研究中应用的主要结果。最后，我们讨论了从γ射线数据推断出的电子光谱中低能破裂的预测。
The current great precision on cosmic-ray (CR) spectral data allows us to precisely test our simple models on propagation of charged particles in the Galaxy. However, our studies are severely limited by the uncertainties related to cross sections for CR interactions. Therefore we have developed a new set of cross sections derived from the FLUKA Monte Carlo code, which is optimized for the treatment of CR interactions. We show these cross sections and the main results on their application for CR propagation studies. Finally, we discuss the prediction of a low-energy break in the electrons spectra inferred from gamma-ray data.
