Direct Evidence of the Pitch Angle Scattering of Relativistic Electrons Induced by EMIC Waves

Geophysical Research Letters, 2020
In this study, we analyze an electromagnetic ion cyclotron (EMIC) wave event of rising tone elements recorded by the Van Allen Probes. The pitch angle distributions of relativistic electrons exhibit a direct response to the two elements of EMIC waves: at
