| Zusammenfassung |
The formation of a zone of energetic electron
precipitation by the plasmapause, a region of enhanced plasma density, following
energetic particle injection during a magnetic storm, is analyzed. Such a region
can also be formed by detached cold plasma clouds appearing in the outer
magnetosphere by restructuring of the plasmasphere during a magnetic storm. As a
mechanism of precipitation, wave-particle interactions by the cyclotron
instability between whistler-mode waves and electrons are considered. In the
framework of the self-consistent equations of quasi-linear plasma theory, the
distribution function of trapped electrons and the electron precipitation
pattern are found. The theoretical results are compared with experimental data
obtained from NOAA satellites.
