摘要
在Tang和Chan所给出的氢原子的2-l极动态极化率的微分表达式的基础上,进一步导出了氢原子电多极动态极化率的解析表达式,从而完全解决了氢原子动态极化率的计算问题.应用此解析表达式,首次计算了氢原子H(2s)-H(2s)-H(2s)体系的三体相互作用系数.
An analytic expression for the 2l-pole dynamic polarizability of hydrogen atom in an arbitrary state is derived from a differential expression obtained by Tang and Chan,and the problem of calculating the 2l-pole dynamic polarizability of hydrogen is solved.As an application,new three-body van der Waals dispersion coefficients for the H(2s)-H(2s)-H(2s) system are calculated from integrals of products of the dynamic polarizabilities of the interacting atoms.
