Escape of atmospheric helium by nonthermal processes
Reviews of Geophysics, 1968Several nonthermal mechanims have been proposed to resolve the discrepancy between the rate at which helium is released from the earth's crust and the average rate of thermal escape of the gas. The various mechanisms are examined critically. Loss of its ions from the polar ionosphere appears to be the most likely mechanism controlling the escape of ...

Physical Parameters of the Atmospheric Escape Layer
Nature, 1960Nicolet1 and Urey2 have made estimates of such physical parameters of the atmospheric escape layer as the height of this critical level, its temperature, and the corresponding scale height, by extrapolation of results of the Rocket Panel3. Since the data of the Rocket Panel extend to a height of only 220 km., considerable extrapolation is necessary ...
