用Geant4模拟程序研究了宇宙线介子在海平面上的角分布。通过将模拟结果与伯克利实验室宇宙射线探测器的测量结果进行比较，对模拟中使用的模型进行了测试。通过实验测量得到了一次粒子的能量和通量。模拟是在从θ = 0°到θ = 70°的每个天顶角上以5°为增量运行的。海平面上的介子角分布估计为I(θ) = i(0°)CoSN(θ)，其中i(0°)是0°处的介子强度，n是介子动量的函数。能量大于1GeV的介子的指数n = 为1.95±0.08，与文献值在误差范围内符合得很好。
Angular distribution of cosmic-ray muons at sea level has been investigated using the Geant4 simulation package. The model used in the simulations was tested by comparing the simulation results with the measurements made using the Berkeley Lab cosmic ray detector. Primary particles’ energy and fluxes were obtained from the experimental measurements. Simulations were run at each zenith angle starting from θ = 0° up to θ = 70° with 5° increment. The angular distribution of muons at sea level has been estimated to be in the form I(θ) = I(0°) cosn (θ), where I(0°) is the muon intensity at 0° and n is a function of the muon momentum. The exponent n = 1.95±0.08 for muons with energies above 1 GeV is in good agreement, within error, with the values reported in the literature.
