Composition of cosmic rays at 1010 to 1013 eV nucleus

Description

The nuclear composition of the cosmic rays around 1010-1013 eV total energy per nucleus has been calculated from recent counter measurements. The abundance of iron in the highest energy range is comparable to the abundance of protons and alpha particles, and increasing with energy. If this trend continues, the highest energy airshower events recorded are caused mostly by iron nuclei, and their extragalactic origin are not sure

Abstract (French)

On calcule la composition nucleaire des rayons cosmiques d'environ 1010 a 1013 eV d'energie par noyau, d'apres les recentes mesures par compteurs. L'abondance du fer dans les plus hautes energies est comparable a celle des proton et des particules alpha et augmente avec l'energie. Si cette tendance continue les evenements enregistres aux plus hautes energies dans gerbes sont causes principalement par les noyaux de fer et on ne peut etre sur de leur origine extragalactique
