Аннотация:A new kinetic model of distribution of interstellar hydrogen atoms in the heliosphere is suggested in this paper. It takes into account global effects associated with charge exchange of interstellar atoms near the heliospheric boundary. The constructed model allows one to find efficiently the detailed distribution of hydrogen atoms over space and velocities. For the axisymmetric steady-state case a comparison is made of the parameters of interstellar hydrogen atoms that were obtained using the classical hot model, two modifications of the improved hot model, and a global self-consistent kinetic gas-dynamic model of the heliospheric interface. The results of calculations of the spectral moments of scattered solar L alpha radiation are presented. They were derived on the basis of different models of distribution of hydrogen atoms in the heliosphere.
