atoms penetrating from interstellar space and others. According to calculations of Le Roux and Fichtner (1997), the change of solar wind speed with the distance r from the Sun can be described approximately as u(r ) Ml(1 - b(r/rtSw )), (2.46.35)

where rtsw is the distance to the terminal shock wave and parameter b ~ 0.13 0.45 depends on sub-shock compression ratio and on injection efficiency of pickup protons. On the basis of Eq. 2.46.35 we can determine the radius of CR modulation region rmod from equation:
