摘要：

An expansion for the Coulomb 1/r(12) interaction is derived which, unlike the classical multipole expansion, converges for all r(1) and r(2). It allows the long-range component of the total Coulomb energy of a system to be written as an infinite series involving the system's multipole moments. The series is convergent if the system is of finite extent and is asymptotically convergent otherwise.
