|Title:||Role of oblique whistler-mode waves in energetic electron precipitation at the lower edge of inner radiation belt|
Agrawal, Bal Mukund
|Abstract:||An attempt has been made to study the precipitation of energetic (keV and MeV) electrons at the lower edge of inner radiation belt in terms of their quasi-linear gyro-resonant interaction with oblique whistler-mode waves. The calculated average pitch angle scattering (~10-1 degree) and lifetimes (~ days and hours only) indicate a significant electron precipitation by these waves into the lower latitude atmosphere. The low calculated lifetimes of energetic electrons and sufficiently high calculated flux of precipitated electrons caused due to gyro-resonant interaction involving oblique whistler-mode waves show that these non-ducted waves are likely to be an effective electron precipitator at the lower edge of inner radiation belt.|
