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.

金属衬底上碱金属覆层的弹性和非弹性氦散射将被用作获取有关其结构和动力学以及缺陷对其结构和相变的影响的附加信息的手段。结果将用于测试当前的理论，并将导致更好地理解吸附质/基质和吸附质/吸附质的相互作用。吸附现象具有重大的基础科学意义，但在技术上也极为重要，例如在催化中；提取、分离、纯化；附着力;合成与加工。
