This paper is one in a series of stimulating reports, (1948 to date), by Chang and Uhlenbeck. There, a number of problems involving the linearized Boltzmann equation were clearly formulated, and methods of solution were developed which were based on full range expansions of the velocity distribution. We start from this formulation, and are able to use a number of their calculations, as well as those of Mott-Smith3; particularly those dealing with the Boltzmann collision operator. As explained in I, the method of solution which we adopt, based on Yvon’s idea of half-range distributions, is quite different. The full range expansions of Chang and Uhlenbeck and Mott-Smith have much in common with Grad’s approach to the nonlinear Boltzmann equation (cf. reference 4).
