dc.description.abstractA new expression for diffusion coefficient D (α) is derived, which is a function of pitch angle (α) dependent kinetic energy of electrons. Pitch angle diffusion of electrons along with amplification o f interacting VLF signals is studied at L= 5.1. Diffusion coefficient D (α) has been found to increase but temporal wave growth (r) and power gain (in dB) decrease with increase in pitch angle. The derived expression for D (α) is found to be convenient for numerical analysis. The results are interpreted in the light of observation/analysis of transmitted signals by Sonwalkar et al. [J Geophys Res (USA), 102 (1997) 14363]. The non-observation of 2.55-2.9 kHz signals is attributed to scarcity of suitable pitch angle anisotropy, A(Er) ·en_US
