超高能核传播

Ultra High Energy Nuclei Propagation

Roberto Aloisio

摘要:

本文讨论了超高能核在天体物理背景中的传播问题。我们提出了一个新的分析计算方案的基础上假设的连续能量损失的动力学配方的粒子传播。该方案不仅可以计算超高能核的通量,而且可以计算原子核在光致蜕变过程中产生的次级粒子(原子核和核子)的通量。

英文摘要:

We discuss the problem of ultra high energy nuclei propagation in astrophysical backgrounds. We present a new analytical computation scheme based on the hypothesis of continuos energy losses in a kinetic formulation of the particles propagation. This scheme enables the computation of the fluxes of ultra high energy nuclei as well as the fluxes of secondaries (nuclei and nucleons) produced by the process of photo-disintegration suffered by nuclei.
