The authors present measurements of electrons made with high energy and pitch angle resolution, made at the equator, looking over a range of L shells in the neighborhood of the nightside trapping boundary. They define the trapping boundary to be the position where the trapped fluxes are equivalent to the background level. The transition region is studied in detail. Fine scale experimental measurements are of use in bringing together theoretical models which attempt to explain precipitating electrons from the outer boundary of the earth's electron radiation belt, with the broad range of measurements which are presently available. They took advantage of the measurement capabilities of the CRRES and SCATHA satellites for this work.
