Ionization by keV election precipitation in the auroral zone
P(論文) The electron fluxes precipitating into the aurora zone were observed by the electron spectrometers (ESM) onboard the Japanese Antarctic sounding rockets S-310JA-5 and -6 at Syowa Station in 1978. The ESM measured successfully the electron fluxes in the energy range of 1 to 10keV at small and n...
