摘要
利用碱金属原子的模型势和稳定变分法,首次计算了异核碱金属原子间的三体相互作用系数.为了说明计算结果的精度,同时计算了碱金属原子的电多级极化率.与其他作者的理论数据和有关实验数据的比较表明,本文所得到的异核碱金属原子间的三体相互作用系数是可靠的.
By utilizing the model potential for alkali-metal atoms and the variationally stable method, the three-body dispersion coefficients for heteronuclear interactions of the alkali-metal atoms are calculated for the first time. In order to illustrate the reliability of the calculated results, the multipolar polarizabil- ities of the alkali-metal atoms are also calculated and compared with those of the previous calculations and experimental data. The results show that the present three-body dispersion coefficients are reliable.
