Scientific paper

Theoretical studies have shown that resonant interactions of electrons with whistler-mode chorus waves can lead to the acceleration of particles to relativistic energies. Observations have shown intense chorus emissions during prolonged substorm activity outside the plasmapause in association with relativistic electron enhancements observed in the same time and space. The electron-chorus resonant interactions have been introduced in the Salammbo physical model along with radial diffusion to calculate phase space density and flux profiles for different magnetic activity conditions. The role of electron-chorus resonant interactions and radial diffusion as individual processes has been investigated and the magnitude of their effects both singly and in combination has been tested. A parametric study of important processes has also been realized.
