Abstract
An analytic estimate is made for radiation from electrons oscillating between magnetic surfaces of the earth's magnetotail. The oscillation is highly anharmonic and occurs within the neutral sheet. An estimate of 4-10 kHz is obtained for the frequency of the electromagnetic radia tion from an anisotropic beam of electrons; this radiation grows to ap preciable amplitude within similar to 2 cycles, and results from a pha se-bunching instability.
