摘要
本文对双原子分子N_2和刚性、有波纹度的Fe(100)表面的相互作用势进行了研究。我们在已有的四体LEPS势模型的基础上,研究了LEPS势性质;得出了和已有实验数据相吻合的势参数,并且研究了N_2分子以不同方式入射到Fe(100)表面时分子一表面相互作用势U_(M-S)。
The interaction potential of a nitrogen molecule with a rigid corrugated Fe (100) surface has been studied theoretically in this paper. The four - body LEPS potential is employed to illustrate the properties of the LEPS potential, to obtain the potential parameters in good accordance with experimental results and to investigate the molecule - surface potential U_(M-S) for different positions of approach and different internuclear seperations.
