Abstract content

Measurements of muon flux in the atmosphere have been performed by Lebedev Physical Institute during sea expeditions in November, 1975 -
March, 1976 period. This survey covered a wide range of latitudes with
geomagnetic cutoff rigidities Rc from 0.8 up to 14.2 GV. The data on muon flux as a function of atmospheric depth ( X~ 10-1000 g/cm2) were obtained. On the other hand based on GEANT4 facilities we have calculated the secondary muon fluxes produced by galactic cosmic rays in the atmosphere at different Rc during solar activity minimum epoch. The experimental and calculation results as well as their comparison are presented in the paper.
