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
