| 英文摘要: | In this study we present calculation of bounce resonant scattering of near equatorially mirroring electrons by fast magnetosonic waves. We first explore the sensitivity of the scattering rates and estimated time scales to a different number of resonances included into calculations. We then explore the sensitivity of calculated rates to the assumed wave normal angle. Our results show that at large radial distances bounce resonant scattering is capable of providing local isotropization of nearly equatorially mirroring electrons on the time scales as short as hours or even days depending on the assumed properties of waves. We also present analysis of the bounce frequencies of electrons and protons at various energies and radial distances and discuss the wave modes that are capable of bounce resonance with these particles. In particular, the importance of bounce resonance as a potential mechanism for the radiation belt remediation is discussed. © 2015. American Geophysical Union. All Rights Reserved. |
