| Abstract: | Relative effectiveness of plasmaspheric hiss and VLF hiss in the inner belt
energetic electron precipitation has been studied. The results show that
plasmaspheric hiss can induce significant precipitation of electrons by causing
small changes in their energy whereas in case of VLF hiss, nearly ten times
higher energy changes are required for similar precipitation. The minimum pitch
angle  m corresponding to peak energy
change varies with L-value in the
same fashion as the minimum wave length ( m) corresponding to peak energy
emission varies with temperature T in
case of black body radiation. The results, further, hint that the plasmaspheric
hiss is more effective in energetic electron precipitation towards the inner
edge (L ~ 1.2) of inner
radiation belt, which is in good agreement with the findings of earlier studies |
