Coronal and interplanetary transport of solar energetic protons and electrons

摘要: We present a new method to separate interplanetary and coronal propagation, starting from intensity variations observed by spaceprobes at different heliolongitudes. In general, decrease in absolute intensities is simultaneously with an increase temporal delays. The coupling of these two effects can be described Reid's model diffusion principle used determine the time constants, t c escape A. addition, least-squares fit parameters transport, assuming radial dependence as λ(r) = λ0(r/1 AU)b. applied solar events 27 December, 1977 1 January, 1978 which were Helios 1, 2, Prognoz 6. Energetic particle data are analysed for 13–27 MeV protons ∼-0.5 electrons. For regions space encountered during mean free path electrons smaller than that protons. Straight interpolation between rigidities leads rather flat rigidity λ(P) ∼ P n 0.17–0.25. This contradicts prediction constant or transition scatter-free propagation below about 100 MV rigidity. three four cases order 0.17 AU, 0.06 AU. we find b ∼- 0.7 exponent variation.
