Extract

In this paper we study the steady-state interplanetary propagation of solar cosmic-rays by means of analytic solutions of the equation of transport. The cosmic-rays are released monoenergetically from a fixed heliocentric radius and redistribute in energy as they propagate. Previous investigations by Goldstein et al. (1970), Urch and Gleeson (1971,1972), and Parker (1965, 1966), were either not general enough or used numerical solutions which could not deal with strictly monoenergetic initial injection nor maintain accuracy over a wide range of particle energies. We use the analytic solutions of Gleeson and Webb (1973) and show the energy changes, the redistribution in energy (or momentum) and the characteristics of the particle flow or streaming.
