Abstract

It is analytically shown that the total absorption of the hadron component of extensive air showers and the transition to the pure electromagnetic cascade cannot cause the observed sharp knee in the cosmic ray energy spectrum. This fact and the absence of proved nuclear models allow the conclusion that the knee origin is astrophysical.

关于宇宙射线能谱中膝盖的起源

摘要

分析表明，广泛的空气喷淋中强子成分的总吸收以及向纯电磁级联的过渡不会在宇宙射线能谱中引起观察到的尖锐拐点。这一事实以及缺乏经过验证的核模型都可以得出这样的结论：膝盖起源是天体的。
