| 摘 要： | 本文从原子间相互作用的物理本质出发，用修正的Tang-Toennies（TT）势模型计算了He-He原子间相互作用的van der Waals势．结果显示修正后的势模型在平衡间距附近及远程部分仍然给出了势能曲线的准确结果，在近程部分则较之TT势给出了与实验符合得更好的结果．

| Abstract: | Based on the physical nature of the interatomic interaction, the van der Waals potential of He-He has been calculated by using the modified Tang-Toennies potential model in the present paper. The results show that the modified TT potential model can not only give the interatomic potential in the near well region and the long-range region accurately, but also give the potential in the better agreement with the experiment than the TT model in the short-range region. |
