THE DIRECT MEASUREMENTS OF MOLECULAR VELOCITY DISTRIBUTION FUNCTIONS.
Abstract
A brief summary of the research conducted is presented. During the investigation it was demonstrated that the Doppler profile of the 5015.67A helium line excited by a beam of 20 kv electrons can be used to measure distribution functions. The first interference free measurements of a distribution function in a free jet expansion were made, and resonance diffusion of the emission by an electron beam was considered relative to a decrease in spacial resolution. The etalon system and the recording system were improved so that nonequilibrium distribution function measurements will be possible in wind tunnel laboratory environments. (Author)
