OF COSMIC RADIATION THROUGH
THE EARTH'S ATMOSPHERE

UDC 539.1

A theoretical model is worked out and a characteristic 
is given for the physical processes occurring in the passage of high-energy 
neutrons and protons through the earth's atmosphere. A mathematical 
model of internuclear and intranuclear cascades is presented. The 
process of nuclear spallation is regarded as consisting of direct 
expulsion of one or several high-energy nucleons from a nucleus and 
de-excitation of the residual nucleus in the form of an evaporation 
cascade. The mathematical model is based on the Monte Carlo method. 
Results of numerically modeling the passage of the proton component 
through an actual atmosphere are presented.
