Midlatitude E-region: an examination of the existence of a corpuscular source. [40 eV to 5. 5 keV]

This report presents data obtained from two rocket flights launched from White Sands Missile Range to investigate energetic electrons and positive ions in the E-region ionosphere below 120 km. The rocket payload was designed to measure these particles in the energy range 40 eV to 5.5 keV. The purpose of the flights was to investigate the possible role of corpuscular radiation in ionospheric E-region processes and as a source of heating in the lower thermosphere at a mid-latitude location.
