COLLISIONS IN IONIZED GASES

Abstract

A study was made of the description and effects of particle interactions in ionized gases. The principal results are: (i) an expansion theorem for the linearized Fokker-Planck collision operator for each component of a two-component fully ionized gas, and (ii) a description of photon scattering from a partially ionized gas. It is shown that the Fokker-Planck collision operator generates a complete, continuous set of velocity-space eigenfunctions, for which high-speed asymptotic forms are found. Since the set is continuous, the expansion formula has the form of a generalized Fourier integral. The effect of neutral atoms on the spectrum of photons scattered by electrons in a partially ionized gas is shown to be primarily a reduction in height and increase in width of the two electron-plasma 'wings.' The scattered photon spectrum is described for several characteristic cases.
