Abstract

At low satellite altitudes, peaks have recently been reported to occur often in the energy spectra of electrons precipitating from the outer edge of the inner radiation belt (Imhof et al., 1973). The energies of the peaks in the L shell interval ~ 1.4 to ~ 1.8 at h min < 0 often decrease very rapidly with increasing L value. This paper complements the previous study by presenting some new data on the distributions in energy of the peaks at a given L value, on the variations in the slope of the energy vs. L value, and on the local times of occurrence. The observations are interpreted in terms of the possible resonant interaction of electrons with VLF waves of a nearly constant frequency over the L range of concern.
