Transfer of dissipating photoelectrons in the magnetosphere.
Abstract
The energy spectra and pitch angle distribution of electrons with energies ranging from 30-150 eV were measured in December, 1968 and in June, 1970 by Kosmos-261 and Kosmos-348. These observations show that when photoelectrons are transferred form the illuminated ionosphere to the magnetically coupled region a marked weakening of electrons with energies lower than 50 eV occurs. At the equatorial boundary of the dayside cusp, photoelectron transfer occurs only up to the trapping boundary of electrons with energies of several tens of keV.
