Electron-Production Rate of Solar and Galactic Cosmic Rays in the Lower Ionospheric D-Region.
Abstract
The heavy-ion component of galactic cosmic rays is found to yield an electron-production rate approximately one-half the magnitude of the proton component. At high altitudes, variations in the cut-off energy level in the middle and high geomagnetic latitudes (physically caused by geomagnetic storms) have a large effect on the electron-production rate of galactic cosmic rays (especially in the transition region between cut-off and no effective cut-off(approximately 68 degrees)); in the 30-to-60-km altitude region, however, electron production is not significantly affected. Solar protons can cause an abnormally high electron-production rate (at high latitudes) to all depths of the ionosphere, indicating a large effect on VLF reflection during solar particle storms.
