摘　　要：本文基于无任何可调参数的势模型计算了碱土金属原子(Be、Mg、Ca、Sr、Ba)与Ne原子间相互作用势,得到的势能曲线及势阱位置和深度与现有的从头计算结果符合较好.本文的计算结果进一步验证了碱土金属原子与稀有气体原子间交换能主要来自碱土金属原子最外层s电子与稀有气体原子最外层p电子之间的交换作用.A potential model without any adjustable parameters is used to calculate the interaction potentials between Be, Mg, Ca, Sr, Ba atoms in the ground state and Ne atoms. The obtained potential energy curves and the positions and depths of the potential wells are in good agreement with the results of ab initio calculations. It is verified that the exchange energies between alkaline earth metal atoms and rare gas atoms mainly come from the outermost s electrons of alkaline earth metal atoms and the outermost p electrons of rare gas atoms.
