Energy Spectra of Splash & Re-entrant Albedo Electrons of Cosmic Radiations

171-173The flux and energy spectra of the splash albedo electrons of cosmic rays moving upwords in the upper atmosphere, are calculated in the energy interval 0.1-10 000 MeV. These are compared with the experimental measurements of the splash albedo electrons in the energy interval 0.1-1100 MeV (The flux and energy spectra of re-entrant albedo electrons in the energy interval 0.1-10 MeV have yet to be measured.), observed in a high altitude balloon experiment carried over Palestine, Texas. These splash albedo electrons return back due to the earth’s dipole field and appear as re-entrant albedo electrons moving downward in the upper atmosphere, approximately having the same flux and energy spectra. Therefore these calculations are also compared with the various observed fluxes and energy spectra of re-entrant albedo electrons. The agreement is good. These low energy electrons will be a substantial source of ionization in the lower D-region of the ionosphere
