Abstract
Based on the concept of collective vibrations of ions in the bulk of metal systems, the frequency of vibrations of an oxygen molecule on the aluminum–cerium alloy surface has been evaluated. Numerical estimation of the physical adsorption isobar has been carried out in accordance with the Henry law using these data and the heats of oxygen adsorption on the surface of this alloy in amorphous and polycrystalline states obtained on the basis of optical experiment data. It has been shown that changes in the alloy’s electronic structure upon splitting of the conduction band for the amorphous state has a significant effect on the qualitative characteristics of the adsorption process.中文翻译:
