Results of measurements of the atmospheric muon flux in the zenith angle range of 85°–95°

Resumo

The results of the study of the near-horizontal muon flux in the zenith angle range of 85–95 degrees are presented. In particular, the so-called albedo muons (atmospheric muons backscattered in the ground to the upper hemisphere are recorded in this range. The data of measurement series performed at the NEVOD-DECOR experimental complex are analyzed for 30 thousand of “live” time hours. Multiple Coulomb scattering of muons in the ground is simulated by theMonte-Carlo method using various models. The measured muon flux intensity is compared with the simulation results.
