摘要

本文提出了一种新方法，用于估算能量超过 \(1.25 \times {{10}^{{19}}}\) eV 的单个事件中宇宙射线的质量组成。它基于对实验数据的联合分析，以及使用 QGSjet-II.04 模型对天顶角达到 60°的空气阵列中阈值能量为 \({{E}_{\mu }} = 1.0 \times \cos \theta \) GeV 的μ介子的模拟结果。使用的数据来自雅库茨克 EAS 阵列的地面和地下闪烁探测器。发现了独立的原子核和其他原生粒子群。

Estimation of the Composition of Ultra-High Energy Cosmic Rays Using the Muon Correlation Method Based on Yakutsk EAS Array Data

In this article a new method is proposed for estimating the mass composition of cosmic rays in individual events with energies above \(1.25 \times {{10}^{{19}}}\) eV. It is based on a joint analysis of experimental data and simulation results obtained using the QGSjet-II.04 model for muons with threshold energy \({{E}_{\mu }} = 1.0 \times \cos \theta \) GeV in air showers with zenith angles up to 60°. The data from ground-based and underground scintillation detectors of the Yakutsk EAS array were used. Separate groups of nuclei and other primary particles were found.
