| Outline of Final Research Achievements |
Some of energetic electrons injected into the inner magnetosphere are accelerated effective to a few MeV energy ranges by whistler mode chorus waves, resulting in rapid formation of the outer radiation belt. The MeV electrons of the outer radiation belt can be scattered into the loss cone by electromagnetic ion cyhclotron wave. The formation and loss processes of the outer radiation belt are successfully reproduced by computer simulations.
