Experimental measurements of the cross sections for radiative scattering of electrons from the neutral species Ne, Ar and Xe have been obtained. The experiments were performed in shock-heated gases from 8000-15,000 degrees K using a rapid scanning spectrometer to measure the absolute intensity of the neutral Bremsstrahlung continuum over the wavelength interval of 2.0 - 5.4 microns in the infrared. The data have been analyzed to obtain the effective nuclear charge squared Z sub i squared, of the species i, doing the scattering using a modified form of the Kramers-Unsold equation, and to obtain the radiative absorption cross section Qa sub i. Experimental information on the temperature and wavelength dependence of the neutral Bremsstrahlung has been determined. The experimental Qas have been compared with calculations based on a simple theory of radiative scattering of electrons from neutral species. Author
