Energy and Momentum Accommodation Coefficients on Platinum and Silver.

Abstract

Acoustical measurements of energy and tangential momentum accommodation coefficients indicate stable and reproducible Pt and Ag surfaces are obtained by heating in a vacuum. EAC and TMAC values are given for He and Ne on the heat-cleaned Pt and Ag surfaces and for these gases on Pt and Ag surfaces after exposure to various adsorbent gases. AC values are also given for the various adsorbent gases on themselves on the heat-cleaned Pt and Ag surfaces. (Author)
