我们描述了氢在金属表面扩散的实验和理论研究。实验系统为H/Pd(111)，我们描述了利用低能电子衍射结合入射光束对表面的电子刺激来研究表面扩散。讨论了电子刺激解吸和无序现象，并对实验进行了解释。从理论上研究表面扩散，采用变分过渡态理论。该技术研究的体系为H/Ni(111)，并与实验进行了比较。
We describe experimental and theoretical studies of hydrogen diffusion on metal surfaces. The experimental system is H/Pd(111) and we describe the utilization of low‐energy electron diffraction in combination with electron stimulation of the surface by the incident beam to investigate surface diffusion. Electron stimulated desorption, as well as disordering are discussed with regard to the interpretation of the experiments. To study surface diffusion theoretically, variational transition state theory is employed. The system studied by this technique is H/Ni(111) and comparison to experiment is given.
