摘要: [1] We have found that efficient acceleration of resonant electrons takes place in a self-consistent particle simulation reproducing whistler-mode chorus emissions. While the majority lose energy contributing to generation emissions, fraction having large pitch angle are simultaneously energized through nonlinear wave trapping by generated A small energetic over 100 keV during 2500 Ωe0−1. We also find such accelerated show characteristic behavior turning their motion from equatorward poleward process, which is explained relativistic (RTA) process. The present study clarifies role significant energization process narrowband
