论文摘要
分析了距轴600 m的阈值阈值和带电颗粒的阈值阈值的数量之比。考虑到具有高于5 EEV的能量的空气淋浴，并且考虑到小于60度的天顶角。将实验数据与QGSJETII-04模型计算的各种原代核的计算，包括伽马射线，表明宇宙射线的质量组成至$ \ sim $ 10 $ 10 EEV主要由质子和氦核组成，并具有少量的重核。数据包括带有非常低的含量的空气淋浴，假定由原发性伽玛射线产生。
The ratio of the number of muons with a threshold of 1 GeV and charged particles at a distance of 600 m from the axis is analyzed. Air showers with energies above 5 EeV and zenith angles with less than 60 degrees are considered. Comparison of experimental data with calculations by the QGSJETII-04 model for various primary nuclei, including a gamma ray, showed that the mass composition of cosmic rays up to energies of $\sim$ 10 EeV mainly consists of protons and helium nuclei, with a small number of heavy nuclei. Data include air showers with a very low muon content, which are assumed to be produced by primary gamma rays.
