The inelastic scattering of 2.4 Å neutrons by two states of pure hydrogen and two states of a mixture of hydrogen and argon (at a similar density) have been studied. From these data relaxation times for the velocity auto-correlation function of each state are obtained and are compared to the predictions of a simple hard sphere kinetic theory. It is found that, although the relaxation time depends on the momentum transfer, for pure hydrogen the prediction is in general agreement with experiment. For the mixture the prediction is about 2.5 times larger than the measured values, which is attributed to the reduction in the 'persistence' of the velocity after a collision.

Space Problem

This paper deals with the analysis of the steady flow of a semi-infinite expanse of rarefied gas bounded by its plane condensed phase by the methods of the discrete kinetic theory. The existence of the solutions of the corresponding boundary value problem is discussed. The relations among the parameters of the flow near the condensed phase and at infinity required for the existence of solutions are established. The problem of condensation of a vapor gas on its own condensed phase is then solved analytically for a particular discrete model and remarkable features of the flow are analyzed.
