Corpuscular ionizing radiation (electrons with energies E/sub e/ = 40 keV) participates together with ultraviolet and x-ray solar radiation and cosmic rays in the formation of the D region of the ionosphere. The relative role of these ionization sources depends day and night on the nature of their daily variations. A series of measurements on M-00 rockets at different times of the day was carried out in order to obtain data on the variations of corpuscular radiation. Magnitudes of electron fluxes at altitudes of 87 km obtained in each of the missile launches are depicted for local times. These data were used to estimate ion-formation rates in the D region of the ionosphere. It is found that a corpuscular source can yield a substantial contribution under moderately disturbed conditions to ionization of the night D region at mid-latitudes. (JFP)
