摘要

摘要明确推导出了上林势的二阶微分方程。这个微分方程的右边是两个麦克唐纳函数\(K_{0}(b r)\)和\(K_{1}(b r)\)的线性组合。这个中心势在许多 QED 问题中都具有重大意义，因为它描述了少电子和多电子原子、离子、μ介子和双μ介子原子/离子以及其他类似系统中真空极化的最低阶修正。

Differential equation for the Uehling potential

The second-order differential equation for the Uehling potential is derived explicitly. The right side of this differential equation is a linear combination of the two Macdonald’s functions \(K_{0}(b r)\) and \(K_{1}(b r)\). This central potential is of great interest in many QED problems, since it describes the lowest order correction for vacuum polarization in few- and many-electron atoms, ions, muonic and bi-muonic atoms/ions as well as in other similar systems.
