摘要
本文首先回顾了稀有气体原子间相互作用势的研究进展,然后用Pade近似计算了色散系数的上下限,再结合实验测量拟合的势阱位置和深度来确定Born-Mayer参数,最后用Tang-Toennies势模型(以下简称TT势)来全面计算稀有气体原子间的相互作用势。本文计算结果与实验值符合得很好,表明用TT模型势来研究闭壳层原子间相互作用势是很成功的。
The reseach advance of the interaction potential between rare gaseous atoms is reviewed. The upper and lower bounds of the multipole Van der Waals Coefficients C6, C8, C10 are established by means of Pade approximation. The Born-Mayer Parameters A, b of these systems are determined from the well width and position adjusted from experimental results. The interaction potential between rare gasous atoms is calculated by employing Tang-Toennies potential model. Our results are in good agreement with the avaiable experimental results for rare gaseous atoms. It's proved that the interaction potential between close shell atoms can be studied by employing TT Potential model.
