             abstract = "The dynamic of Earth's magnetosphere can be disturbed by solar 
                         wind structures, such as Coronal Mass Ejection - CME, and change 
                         the dynamic of the outer and inner magnetosphere. Those 
                         perturbations can generate waves in a wide frequency range, such 
                         as whistler-mode chorus waves (from hundreds of Hz up to tens 
                         kHz), which can be observed almost simultaneously with the arrival 
                         of solar wind structures in the magnetosphere. It means that the 
                         trapped particles' dynamic in the outer radiation belt can be 
                         violated, causing a direct impact on the population of the outer 
                         radiation belt, which is formed primarily by electrons. This 
                         impact may occur from different dynamic mechanisms, such as radial 
                         diffusion, pitch-angle scattering, magnetopause shadowing, and 
                         others. The main goal of this case study, which occurred on 
                         October 12, 2012, is to identify the pitch-angle scattering 
                         mechanism from the resonance between chorus and relativistic 
                         electrons using the Van Allen probes and ACE satellite data. The 
                         outer radiation belt's electron flux enhancement (flux increase) 
                         and dropout (flux decrease) are analyzed from the characterization 
                         of the wave packets (sub-elements) and the calculation of the Wave 
                         Normal Angle (WNA) during the influence of a CME. Therefore, this 
                         work will characterize the wave's sub-elements during the dropout 
                         and enhancement of the outer radiation belt to identify the main 
                         differences in the physical processes responsible for the 
                         high-energy electron flux variability in the outer radiation 
                         belt.",
