The subject of wave-particle interactions inside the magnetosphere has become an increasingly active area of research in recent years. Of the many interactions and instabilities that have been discussed in the literature those dealing with gyro-resonant interactions have received considerable attention. A recent review by Gendrin (1972) on these types of wave-particle interactions summarizes the present state of the theories and points out that “uncertainties about the anisotropy of the particle distribution functions are a heavy handicap for obtaining good comparisons between theory and experiment.” The present paper presents conclusions drawn about the pitch angle distribution of > 40 keV electrons in the outer radiation zone which should add some insight into the behavior of this often studied but not well understood component of the magnetospheric particle population.
