Abstract
An experimental comparison of two widely employed methods of determining accommodation coefficients is presented; these are the method of free molecular flow and the method of the temperature jump. The values of the coefficients which have to be introduced into the computing relationships of the temperature-jump method in order to obtain the true values of the accommodation coefficient are determined, this method being theoretically the less rigorous. Correction factors are determined for both monatomic and polyatomic gases.
