Variations of the Energy and Generation of the Spectrum of Cosmic Rays in Interplanetary Space
Abstract
Consideration is given to the modulation of the cosmic ray spectrum in the region of solar windcosmic ray interaction in terms of functions which have a pronounced maximum at prescribed values of particle energy. Cosmic ray propagation is regarded as occurring in a spherically symmetric region filled by radially moving plasmas with scattering properties described by a diffusion coefficient. The coefficient is independent of particle energy and proportional to the distance from the sun, and for constant diffusion is expressed by infinite sums of degenerate hypergeometric functions. The spectrum with a pronounced maximum is formulated for a modulation region boundary in terms of a boundary problem which includes the density and momentum of the modulation region. High energy particles are determined to be transferred towards increased momentum, with a tendency to leave the modulation region.
