Pitch Angle Distributions of Energetic Electrons in the Equatorial Regions of the Outer Magnetosphere — OGO-5 Observations
Pitch angle distributions (PAD) of energetic electrons relate to a wide variety of magnetospheric processes. Wave-particle interactions (turbulence, instabilities) act on a time scale comparable to the particle gyro period; betatron acceleration is important on time scales of the bounce period to minutes; and drift-shell effects are important on time scales of the azimuthal drift period. A study of pitch angle effects can provide important information on the static and dynamic aspects of field topology. Our interest in this paper is primarily with the drift shell effects.
