摘要：By analyzing the Van Allen Probe B observations and 2-D simulations, we found that the competitive influences of different plasma waves on the pitch angle distribution of energetic electrons (hundreds of keV) depend on relative intensity of waves and density of ambient plasmas. In the high-density
plasmasphere (>70 cm−3), plasmaspheric hiss is able to effectively remove small pitch angle electrons (<60°),
while the participation of intense magnetosonic (MS) waves merely increases part of large pitch angle electrons
(>60°). The combined diffusions by the two waves create pancake distribution.
