Abstract
In the present paper we consider a possibility of using stochastic simulati on (Monte-Carlo) technique approach to the study of Galactic Cosmic Fray pr opagation in the Heliosphere. We developed a technique for calculation of t he cosmic ray propagation in a spherically symmetric steady state approxima tion of the Heliosphere. A comparison of the calculation results with those obtained by other methods as well as with an analytical approximation show s a good agreement. Besides, in the frameworks of the approximation used, w e calculated the solar modulation of monoenergetic fluxes of Galactic Cosmi c Rays entering the Heliosphere, in the particle's energy range 0.1 - 15 Ge V. We studied the details of the modulation in their dependence of the init ial particle's energy. In particular, a linear scaling of particle's energy losses us, diffusion time is shown.
