LOW-ENERGY ELECTRONS MEASURED BY THE COSMOS-3 AND COSMOS-5 SATELLITES

摘要: Accelerating fluorescent indicators on the Cosmos-3 and Cosmos-5 satellites registered very soft electrons, their energy being in range of 0.04-5 keV. They were observed mostly sunlit portion orbit. Their mean intensity was ~ 5 x 108 electrons per cm2 sec steradian had tendency to rise with height. pitch angle distribution nearly isotropic j markedly different from such distributions for harder electrons. Реаюме: С помощью спутников „Космос 3" и 5" на высотах 2001600 км были зарегистрированы очень мягкие электроны, энергия которых заключена в пределах 0,04-4 кэв. Они наблюдались преимущественно освещенном участке орбиты, причем их интенсивность составляла среднем ~5.108 эл/см2 сек стерад имела тенденцию к увеличению с ростом высоты. Распределение по питч-углам было близко изотропному резко отличалось от распределения более жестких электронов. 1. Electrons 40 eV-5 keV The permitted detection a wide [1, 2].
