Abstract

Parameterizations of double nucleon removal from the electromagnetic and strong interactions of cosmic rays with nuclei are presented. These parameterizations are an extension of previous single nucleon removal parameterizations and combined they represent the dominant part of the electromagnetic dissociation encountered by a cosmic ray on its traversal through matter. Such parameterizations should be very useful in studying cosmic-ray transport through the interstellar medium, the Earth's atmosphere, spacecraft walls, and extraterrestrial matter.

摘要

本文给出了宇宙射线与原子核电磁相互作用和强相互作用中双质子移除的参数化描述。这些参数化描述是先前单质子移除参数化描述的扩展，综合起来它们代表了宇宙射线在穿过物质时所遇到的电磁离解的主要部分。这样的参数化描述在研究宇宙射线通过星际介质、地球大气层、航天器壁和外星物质的传输过程中应该会非常有用。
