摘要: A model is developed to calculate the effect of atmospheric spreading on flux and angular distribution protons in homogeneous auroral arcs. An expression derived that indicates atmosphere as a function distance from arc center, neutral scale height, width, initial distribution. The results agree favorably with those based Monte-Carlo calculations. From these enhancement factors needed compute original proton current above are obtained. technique indicated for determining incident rocket-based measurements width
