摘要

假设超高能量宇宙射线来自河外，讨论了能量在1019ev以上的宇宙铁核从源向银河系的传播。在河外空间，宇宙核与背景辐射相互作用，不可避免地分裂。分析了到达地球的铁核的比例，以及它的能量如何取决于与宇宙射线源的距离。发现铁核的能量可以用来确定对其源距离的限制。

Iron Nuclei in Ultra-High Energy Cosmic Rays Near the Earth

The propagation of cosmic iron nuclei with energies above 10¹⁹ eV from their sources to the Galaxy is discussed by assuming that cosmic rays at ultra-high energies are of extragalactic origin. In extragalactic space, cosmic nuclei interact with background emissions and inevitably fragment. An analysis is performed of the fraction of iron nuclei reaching the Earth and how its energy depends on the distance from cosmic ray sources. It is found that energies of iron nuclei can be used to determine restriction on the distances from their sources.
