本文提出了一个计算两个原子（其中一个或两个都处于激发态）间体助货车德瓦耳斯相互作用势的公式。通过绿色函数考虑材料环境的任意布置的存在。由此得出的公式支持两个相互矛盾的调查结果之一。我们的公式的一致性进行了研究，通过将其应用于自由空间中的两个原子的情况下，并将所得的表达式与从激发原子和小电介质球之间的限制Casimir-Polder势中发现的表达式进行比较。
We present a formula for the body-assisted van der Waals interaction potential between two atoms, one or both being prepared in an excited energy eigenstate. The presence of an arbitrary arrangement for a material environment is taken into account via the Green function. The resulting formula supports one of two conflicting findings recorded. The consistency of our formula is investigated by applying it for the case of two atoms in free space and comparing the resulting expression with the one found from the limiting Casimir-Polder potential between an excited atom and a small dielectric sphere.
