Accurate coefficient of the Axilrod–Teller triple-dipole term for three hydrogen atoms

Abstract

Using the very accurate first order perturbation wave function reported recently for the van der Waals interaction between two ground-state hydrogen atoms, we derive an accurate coefficient of the Axilrod–Teller triple-dipole term for three ground-state hydrogen atoms, which is an important leading term of the nonadditive three-body long-range force.
