Helium Scattering from Incommensurate Alkali Metal Overlayers

金属衬底上碱金属覆盖层的弹性和非弹性氦散射将被用作获得关于其结构和动力学以及缺陷对其结构和相变的影响的额外信息的一种手段。结果将用于测试当前的理论，并将导致更好地理解吸附物/底物和吸附物/吸附物相互作用。吸附现象不仅具有重大的基础科学意义，而且在催化、提取、分离和提纯、附着、合成和加工等方面也具有极其重要的技术意义。

Elastic and inelastic helium scattering from alkali-metal overlayers on metal substrates will be used as a means of obtaining additional information on their structures and dynamics, and on the effects of defects on their structures and phase transitions. Results will be used to test current theory and should lead to better understanding of adsorbate/substrate and adsorbate/adsorbate interactions. %%% Adsorption phenomena are of great fundamental scientific interest, but are also extremely important technologically e.g. in catalysis; extraction, separation and purification; adhesion; synthesis and processing.
