Scientific paper

The velocity distribution of hydrogen atoms in the exosphere was measured with the aid of the absorption cell of a Lyman-alpha photometer flown on the OGO-5 spacecraft. The measurement parameter is the reduction factor R, which is the fraction of total Ly-alpha emission which passes through the cell when a given optical depth is reached. The distribution of R at various distances from earth was compared with R computed from a variety of Chamberlain models. It was possible to find values of three parameters (density at exobase level, temperature at exobase level, and satellite critical radius) which describe an exospheric model of Chamberlain and which provide a good fit to the observations. This fact lends strong support to the theory of evaporation and escape of H from an exobase level, developed by Chamberlain (1963).
