1. Introduction . — If gas atoms, having energy corresponding to a temperature T 2 , are incident on a solid surface at a temperature T 1 , then the reflected atoms will have a mean energy corresponding to some new temperature T 2 ', which is a function of T 1 and T 2 . For simplicity it is convenient to define Knudsen’s thermal accommodation coefficient as α = lim T 1 → T 2 → T T' 2 - T 2 / T 1 - T 2 . The accommodation coefficient depends on the nature of the gas atom, the nature of the solid surface, and the temperature T. Accommodation coefficients have been measured by various workers, and the present paper is an attempt to give a theoretical explanation of the results of Roberts, who has measured the accommodation coefficient for helium on tungsten at various temperatures, taking particular precautions to obtain a clean surface.

Laser-induced incandescence (LII) is used to measure the thermal accommodation coefficient between soot sampled from a well-characterized flame and various monatomic and polyatomic gases. These measurements show that the thermal accommodation coefficient between soot and monatomic gases increases with molecular mass due to the decreasing speed of incident gas molecules and corresponding decrease in surface deformation rate, and that energy is transferred preferentially from the surface to the translational mode of the polyatomic gas molecules over internal energy modes.
