The interaction potential was constructed by means of the pair-potential addition method for theLi/Li(100) system with defects. The adsorption and diffusion of a Li atom on the Li(100) surface with the defects of the terraces, kinks and vacancies etc. were investigated. The concept of the ability and network of the capture was put forward and analysed on the basis of results of the binding energy and activated barrier for the adsorption and diffusion on the surface with the defects.
