THE formation of a ledge in the electron distribution functions during Landau damping produces steep gradients at the boundaries of the disturbed region of the distribution function. This makes the pitch angle distribution sufficiently anisotropic to amplify a gyroresonant whistler mode perturbation at the appropriate frequencies.
