Abstract
In two earlier papers experiments have been described on its measurement of the accommodation coefficient of helium with a tungsten surface free from films of adsorbed gas. Similar experiments have now been carried out with neon. The experimental technique was exactly the same as with helium and has been fully described in the second of the earlier papers. The values of the accommodation coefficient of neon at 79°, 195°, and 295°K. are given in the table together with the values for helium, and are plotted as a function of the temperature in fig. 1. The same wire was used as in the helium experiments so that the results for both gases will be equally affected by any roughness of the surface. The results have been confirmed using a second wire.
